feat(ui): add interface, terminal, editor font size and spacing settings - #2224
This PR adds font size and spacing settings to the UI tab.
Settings
Interface font size (50-200%), Terminal font size (8-32 px), Editor font size (8-32 px), and Spacing density (50-200%). Each has a stepper and a reset.
A live preview that follows the steppers before the user presses Save.
How it works
Each value maps to one CSS variable on <html>. A value that is not set removes the override, so the stylesheet default applies.
With nothing set, the layout and the sizes of code, diff, and terminal blocks do not change. The editor size reaches the diff view only while a value is set (a class on <html>).
The preview sets each unset value to initial. A value saved on <html> cannot leak into the preview, so a reset shows before Save. The preview uses the same fallbacks as the live UI.
Review notes
The four settings go through the updateSettings message. Reset values are sent as null so that they clear the stored value.
The review gate flagged that the four values were part of a save that was not atomic. The save pipeline changes below fix that. See "Save pipeline changes".
Most of the diff is the 17 locale files. Only the ui.appearance strings are added.
Save pipeline changes
The "Persistence Integrity" check reported that the four appearance values are saved in a loop that can stop half way. A failed write left some values stored and the rest not, and the webview could not tell. The changes below fix that, and nothing else about how settings are applied. The API configuration, telemetry, and debug messages are sent immediately, exactly as before, and every side effect of a setting runs in the same place as before.
webviewMessageHandler.ts, updateSettings: the four appearance values (interfaceFontScale, terminalFontSize, editorFontSize, spacingScale) are saved all-or-nothing. Each is recorded, with the value it had, right before it is written. If a write fails, the ones this save already stored are put back in reverse order, and so is the one whose own write failed, in case it changed the stored value before failing. The store is shared by the sidebar and the editor tab, so saves can overlap. The writes to one key form a chain. A write is put back only while it is the latest one and the stored value is still what it wrote, so a newer save's value, and a change made outside a save (an import), are kept. A write that fails while a newer one is pending is taken out of the chain, so if the newer one fails too, it restores what was stored before either of them, in whichever order they fail. Writes of one appearance value run one at a time, from every save and every rollback and across providers, and each stays in line until it has reached durable storage, so a slower write cannot complete after a newer one and overwrite it. A write that fails does not hold up the ones behind it. Writes that have finished are taken out of the chain, so nothing is kept about them once the saves are over. The result is posted as settingsSaveResult (success or the error), also when the state refresh fails, and the refresh runs after the values were put back.
The four appearance values are validated in the extension host, with the schemas they are defined with (an integer within its bounds, or null for a reset), before any side effect runs or any setting is stored. An invalid value changes nothing, not even the valid settings sent with it. The save fails with an error and the webview is told. The webview is not trusted: the stepper's limits do not bind a message that was written by hand. Other settings are not checked, as before.
A failure while writing any other setting follows the existing error path, as before, with one addition: the webview is told the save failed (it is waiting for the result), and then the error is rethrown. No error is shown for it, as before. Every other setting is written exactly as before, and the loop itself is unchanged.
The error shown for a failed appearance save does not claim a full restore: it says some settings may be left partly changed.
Not part of the transaction, on purpose: every other setting, and the side effects that run in place while saving (the language, speech, the terminal settings, the command lists in VS Code configuration, the MCP servers, the destructive command guard install). They behave as before and are not undone by a failed save.
SettingsView.tsx: a save that changes an appearance value waits for the host's answer. (A save that changes a time or date value already waited on main, through displayChanged, and still does; this PR does not extend it to any other setting.) For that save, Save is disabled while it is pending, and the "unsaved changes" flag clears only when the host reports success, so a failed save keeps the edits and can be retried. An edit made while it is pending keeps the flag. Request ids (saveRequestId.ts) combine a per-load id with a counter, so an answer from an earlier mount or before a reload cannot match a later save. Every other save behaves exactly as before: no request id, nothing to wait for, and the flag is cleared at once. The existing SettingsView tests for those saves are unchanged.
MCP switch inside a save with appearance values (mcpEnabledChanges.ts, McpHub.handleMcpEnabledChange): the objective is the same all-or-nothing save. The switch is applied in that save, and the wait for it is bounded like every other store of the save, so a disconnect that never finishes cannot keep the appearance records for good. A change cannot be cancelled, so a bounded wait needs three things, each as small as it can be: changes of the switch go one at a time per hub with at most one waiting behind the one under way (a newer value replaces the waiting one, and a retried save joins the change under way, so a stalled change cannot make a queue grow or start a second disconnect on a closing transport); once the changes in line have settled, one reconciliation per hub brings the hub back to the stored setting; and a hub that was disposed applies no change. A save without appearance values awaits the change exactly as before.
Plain settings (config/storeInOrder.ts, config/giveUp.ts): in a save with appearance values the wait for each store is bounded, and a store cannot be cancelled, so a store that timed out may land after the write of a later save, an import or the public API. Stores of one key therefore go one at a time, in the order the writes were made (a save, writeValuesThroughWriteChain for imports and the API). A write that has not started is taken back when its save times out or its provider is disposed (an AbortSignal per save, aborted by ClineProvider.dispose), and so is an MCP change that waits behind another (dropped when no other save waits for it); a write that has started cannot be taken back. The reconciliation after a stalled MCP change holds providers only weakly and asks none that was closed.
SettingsView.tsx: a refresh after an import takes an appearance value only when the import says it stored it, so an edit of a value that another provider changed is kept; every setter that has its own handler records its edit, so a late refresh keeps it.
packages/types: the settingsSaveResult message type. common.json (18 locales): errors.settings_save_failed, shown when a save is rolled back.
Test Procedure
pnpm check-types passes in webview-ui, src, and packages/types.
Webview tests pass. New tests cover the appearance save and reset, the ExtensionStateContext hydrate and update path, and the save result flow (success, failure, edit during a save, late answers).
Extension tests cover the all-or-nothing save (restore order, a newer value is kept, a failing restore, no request id, a failed state refresh).
A Playwright snapshot covers the preview in four themes, with set values and with a reset while <html> holds saved values.
Manual: open Settings > UI. Change each value. Check the preview. Press Save. Check the chat. Reset each value.

The PR adds four configurable appearance settings with controls and a live preview. It updates host and webview state, settings saves, imports, and configuration writes to handle validation, ordering, rollback, partial outcomes, and late refreshes. It also coordinates MCP enablement changes and adds tests, visual fixtures, and translations.
Adds four appearance settings with bounds, defaults, CSS variables, steppers, and a live preview. Chat, code, terminal, Markdown, and diff rendering use appearance values. Tests, visual fixtures, gallery stories, and translations cover these changes.

Merge Risk: Low · previous review 52e70
The appearance settings and their save, rollback and import-refresh handling look largely sound. A handful of narrow edge cases and test-quality items remain open and are worth owner awareness. The mutation-diff CI check is still red and needs a maintainer decision before merge.

Explanation
Appearance write ordering, rollback, and import/API integration support the appearance save requirements in [#2222]. However, webviewMessageHandler.ts also serializes autoApprovalEnabled writes. This unrelated toggle is outside the appearance feature and is not needed to implement its requirements.
Resolution
Remove the autoApprovalEnabled write-ordering change. Keep write ordering for appearance values and the import/API paths that can write those values.
Full details: Security Boundaries
Explanation
The auto-approval off switch can fail to take effect. webviewMessageHandler.ts:2428-2434 queues the disable behind an earlier store. If that store stalls, the UI shows auto-approval as off, but the host cache remains true. Task.ts:1952-1953,1988-1995 then uses that value to approve eligible actions without a prompt. Before this change, the disable updated the cache immediately.
Resolution
Apply disables to the effective host policy immediately while preserving ordered persistence. Prevent a late store from re-enabling auto-approval. Add a regression test for a stalled store followed by a disable.
Full details: Persistence Integrity
Explanation
A queued settings save can be lost without a failure notice. webviewMessageHandler.ts:970-979 now queues each setting behind earlier writes. If an earlier language write stalls, a later save that changes only soundEnabled waits at language. SettingsView.tsx:569-570,670-673 sends no request ID for that save and clears the unsaved flag immediately. If its provider is then disposed, ClineProvider.ts:980-985 aborts the queued write, and the handler never reaches soundEnabled. The user receives no save result.
Resolution
Acknowledge every settings save before clearing its unsaved flag. Preserve queued saves through provider disposal, or report cancellation and retain the edits for retry.
Full details: Regression Evidence
Explanation
The interface scale has no focused coverage for settings descriptions. index.css:31 changes the text-sm token, which NumberStepper.tsx:146 uses. The UI settings snapshot uses the default scale, while the scaled consumer tests check chat, terminal, diff, code, and tool rows. A regression that leaves settings descriptions unscaled can pass those checks.
Resolution
Add a Playwright component test that applies and clears the interface scale, checks a settings description’s computed size, and captures the scaled settings UI.
Full details: Lifecycle Resource Cleanup
Explanation
The new autoApprovalEnabled queue can retain a disposed provider. webviewMessageHandler.ts:2431-2433 queues a closure without an abort signal. If an earlier write of that key never settles, storeInOrder.ts:14-21,64-81 keeps the closure and its provider indefinitely. ClineProvider.ts:983-985 cannot remove this entry on disposal because it has no owner controller.
Resolution
Register the toggle write with a provider-owned abort controller, pass its signal to storeInOrder, and release the controller when the write settles. Add a test for disposal while the toggle waits behind a stalled write.

## Unit & State Tests (Vitest + JSDOM)
- When a regression can be proven with a component or webview integration test, keep it in `webview-ui`. Do not promote it to e2e just because the UI is hosted inside VS Code.
[warning] 36-36: This synchronous effect update causes an extra render: Calling setState synchronously within an effect can trigger cascading renders. Prefer deriving or initializing the value before render. If the effect must read a browser API after mount, treat this as advisory or suppress it with // react-doctor-disable-next-line react-hooks-js/set-state-in-effect.
Effects are intended to synchronize state between React and external systems such as manually updating the DOM, state management libraries, or other platform APIs. In general, the body of an effect should do one or both of the following:
Update external systems with the latest state from React.
Subscribe for updates from some external system, calling setState in a callback function when external state changes.

## Visual Tests (Playwright Story Gallery)
### When a UI change needs a snapshot
If your PR changes anything a user would notice at a glance — layout, spacing, theme tokens, brand elements, gradients, mask/blur effects, hover/empty/error states — **add a `*.visual.tsx` snapshot to the same PR**. Do not attach screenshots to the PR description as evidence; commit the baseline instead so future PRs get regression coverage automatically.
… API; take back queued stores and MCP changes on timeout and disposal; chat font size not validated here; keep unsaved edits through an import refresh
Out of Scope Changes: chatFontSize is no longer validated by this PR (only the four new values are); a test pins that it is stored as before.
Security Boundaries / Persistence Integrity: stores of one key now go one at a time in the order the writes were made, for the saves and for writeValuesThroughWriteChain (imports, the public API, a new task's configuration), so a timed-out enable of an approval setting cannot land after, and overwrite, the import that turned it off. A write that has not started when its save times out is taken out of the line (AbortSignal), so it is never stored later. There is no replacing of a waiting write any more: every caller gets its own outcome, and the middle of three overlapping saves is stored too (it is not reported stored without being stored). Tests: the timed-out enable followed by the disabling import (final value false, the enable never started; mutations on the signal fail it), unit tests of the line (order, failure, abort, an aborted write behind a stalled one, 50 timed-out callers leave nothing), and of the import and API path through writeValuesThroughWriteChain.
Persistence Integrity (import refresh): a refresh after an import no longer replaces a value that the user has edited here when the import did not store it (appearance or not); one test per dedicated setter, mutation-checked.
Lifecycle Resource Cleanup: ClineProvider.dispose takes back the stores and MCP changes that its saves queued and that have not started (giveUpAllOf); a started one goes on. Tests: a stalled store and a stalled MCP change with a waiting store and a waiting MCP change behind them, disposed: the waiting ones never start (a mutation on the abort fails it); the provider test pins the call.

- Around line 963-979: Update the save flow around storeInOrder so MCP
reconciliation runs after the relevant ordered store settles, including stores
that reject after timing out. Ensure reconciliation observes the latest result
after later stores have had their turn and respects current hub state; do not
reconcile immediately on timeout or store failure while an earlier store may
still change the cache.

Failed pre-merge checks:
- Security Boundaries:
Coordinate the direct auto-approval toggle with queued writes. Prevent older
queued enables from overriding a later disable. Add a regression test for a
delayed import followed by disabling auto-approval.
- Persistence Integrity:
Keep unrelated unsaved edits tracked across partial-import refreshes. Track
edits made after an import answer separately for late-refresh handling. Add a
regression test with two partial refreshes and an intervening live-state change.
- Lifecycle Resource Cleanup:
Give each pending MCP waiter its own promise. Reject and detach an aborted
waiter without cancelling the shared change needed by other waiters. Add a test
with a stalled change, two queued providers, and disposal of one provider.

- Line 2683: Update the test that modifies mockClineProvider.contextProxy so
cleanup runs even when an assertion fails: wrap the modified test body in
try/finally, delete the temporary setValues property in finally, and restore the
setValue mock implementation to real there as well.
- Around line 2646-2659: Replace the inline
mockClineProvider.contextProxy.setValues implementation with the real
ContextProxy.setValues method, substituting only the storage boundary needed by
the test. Keep the test exercising production setValues behavior and its actual
storeKey contract rather than duplicating its per-key fan-out logic.

- Around line 235-240: Update the dedicated-setter test cases so the second
partial refresh changes the key to a per-case value that differs from c.late,
while retaining the shared answered value for other cases; use distinct override
values for debug and experiments. Assert after each refresh that the user's edit
remains unchanged, so the test fails if edit tracking no longer protects it.
Review comments at @webview-ui/src/components/settings/SettingsView.tsx:
- Around line 353-355: Clear editedSinceImportAnswer when the user discards
edits in onConfirmDialogResult, alongside the existing edit-tracking cleanup, so
a later refresh can apply stored values for those keys.

Notes on the failed pre-merge checks (latest head):
Persistence Integrity: valid, fixed. An import that failed after it had stored global settings (a step after them: the current profile, the provider settings, the list of profiles) did not name those settings, so the form did not adopt their stored values. The partial outcome now names every global setting that the import stored before the failing step, in addition to what a failed write itself reports. Tests: a provider-settings write failure and a profile-list failure after an appearance value was stored (the stored keys are named); a failure before anything was stored names none.
Lifecycle Resource Cleanup: valid, fixed. Each saved caller of an MCP change (the running one or the waiting one) is now a removable registration with its own promise; a caller that gives up is taken off, its callbacks and signal listener go with it, and the change and the other callers are untouched. Test: 200 saves give up against a change that stays stalled and every one is taken off, while the save that stays gets its change applied.
Out of Scope Changes: not changed. The auto-approval toggle goes through the same per-key line only because this PR makes imports and API writes queue behind earlier writes of a key; without it a delayed import that enables auto-approval could land after the user switched it off (a previous run of this check asked for exactly that). It is one line plus a test, and it is a consequence of the ordered writes, not an extra feature. If the maintainers prefer, the ordered writes can be split out together with it.

110-110: A pending change can resolve without being applied while the hub state is still last.
When succeeded && next.value === value, the code calls settle(next) and skips the change. This is correct only if the hub holds value. changes.last is not updated here, which is correct. But a failed predecessor already clears last through the rejection path, so this branch cannot be reached after a failure. No defect found. Past reviews already covered the failure and reconciliation paths.

Learning: Lifecycle resource cleanup: Fail only when a concrete changed lifecycle path can leak a listener, watcher, provider, timer, task, or other resource, or can duplicate work after cancellation, disposal, or restart. Cite the changed path and a plausible triggering scenario; pass when no such changed path exists.
Persistence Integrity: valid, fixed. The effect that resets the form when the profile or the mode changes replaced the whole form with the live state, so a failed import that changed the profile or the mode dropped an unrelated pending appearance edit and its unsaved status, before the import's own refresh could keep them. That reset is now skipped when the state comes with a refresh of a failed import (which takes what the import stored and keeps every other edit); a switch made elsewhere still resets the form. Tests: a failed import that changes the mode and the profile while a terminal-size edit is pending (the edit, the unsaved status and the next save are kept), and the control that a switch without such a refresh still resets; removing the check fails the first.
Lifecycle Resource Cleanup: valid, fixed. When a waiting change started, its saves moved to the running change, but a save that gave up afterwards was removed from the old, empty one and stayed registered. A registration now moves with its save, and giving up removes it from the change it is registered with. Test: a stalled change that has taken over saves, two of which give up: they are answered at once, are not answered a second time when the change settles, and the save that stays gets its change; the old removal fails it.
Out of Scope Changes: unchanged, as in my earlier note: the auto-approval toggle is in the key's line only because this PR makes imports and API writes queue behind earlier writes; without it a delayed import could re-enable auto-approval after the user switched it off.

Prevent older import snapshots from reverting cached settings.
If two partial-import refreshes overlap and the older snapshot arrives last, SettingsView accepts its different stamp and can replace newer non-appearance values. A later Save can persist those stale values. Reconcile out-of-order refreshes without discarding settings reported by either import.

Apply the timeout inside the ordered write
If an earlier timeout store stalls, an appearance save can apply a new live timeout and then drop its queued store after 15 seconds. Terminal commands can then use a timeout different from the stored setting. The failure refresh does not reset the live timeout.
Move the setter into the ordered callback so a dropped write cannot apply it.

This PR adds font size and spacing settings to the UI tab.

How it works

updateSettingsmessage. Reset values are sent asnullso that they clear the stored value.ui.appearancestrings are added.Save pipeline changes
The "Persistence Integrity" check reported that the four appearance values are saved in a loop that can stop half way. A failed write left some values stored and the rest not, and the webview could not tell. The changes below fix that, and nothing else about how settings are applied. The API configuration, telemetry, and debug messages are sent immediately, exactly as before, and every side effect of a setting runs in the same place as before.
webviewMessageHandler.ts,updateSettings: the four appearance values (interfaceFontScale,terminalFontSize,editorFontSize,spacingScale) are saved all-or-nothing. Each is recorded, with the value it had, right before it is written. If a write fails, the ones this save already stored are put back in reverse order, and so is the one whose own write failed, in case it changed the stored value before failing. The store is shared by the sidebar and the editor tab, so saves can overlap. The writes to one key form a chain. A write is put back only while it is the latest one and the stored value is still what it wrote, so a newer save's value, and a change made outside a save (an import), are kept. A write that fails while a newer one is pending is taken out of the chain, so if the newer one fails too, it restores what was stored before either of them, in whichever order they fail. Writes of one appearance value run one at a time, from every save and every rollback and across providers, and each stays in line until it has reached durable storage, so a slower write cannot complete after a newer one and overwrite it. A write that fails does not hold up the ones behind it. Writes that have finished are taken out of the chain, so nothing is kept about them once the saves are over. The result is posted assettingsSaveResult(success or the error), also when the state refresh fails, and the refresh runs after the values were put back.nullfor a reset), before any side effect runs or any setting is stored. An invalid value changes nothing, not even the valid settings sent with it. The save fails with an error and the webview is told. The webview is not trusted: the stepper's limits do not bind a message that was written by hand. Other settings are not checked, as before.SettingsView.tsx: a save that changes an appearance value waits for the host's answer. (A save that changes a time or date value already waited onmain, throughdisplayChanged, and still does; this PR does not extend it to any other setting.) For that save, Save is disabled while it is pending, and the "unsaved changes" flag clears only when the host reports success, so a failed save keeps the edits and can be retried. An edit made while it is pending keeps the flag. Request ids (saveRequestId.ts) combine a per-load id with a counter, so an answer from an earlier mount or before a reload cannot match a later save. Every other save behaves exactly as before: no request id, nothing to wait for, and the flag is cleared at once. The existingSettingsViewtests for those saves are unchanged.mcpEnabledChanges.ts,McpHub.handleMcpEnabledChange): the objective is the same all-or-nothing save. The switch is applied in that save, and the wait for it is bounded like every other store of the save, so a disconnect that never finishes cannot keep the appearance records for good. A change cannot be cancelled, so a bounded wait needs three things, each as small as it can be: changes of the switch go one at a time per hub with at most one waiting behind the one under way (a newer value replaces the waiting one, and a retried save joins the change under way, so a stalled change cannot make a queue grow or start a second disconnect on a closing transport); once the changes in line have settled, one reconciliation per hub brings the hub back to the stored setting; and a hub that was disposed applies no change. A save without appearance values awaits the change exactly as before.config/storeInOrder.ts,config/giveUp.ts): in a save with appearance values the wait for each store is bounded, and a store cannot be cancelled, so a store that timed out may land after the write of a later save, an import or the public API. Stores of one key therefore go one at a time, in the order the writes were made (a save,writeValuesThroughWriteChainfor imports and the API). A write that has not started is taken back when its save times out or its provider is disposed (anAbortSignalper save, aborted byClineProvider.dispose), and so is an MCP change that waits behind another (dropped when no other save waits for it); a write that has started cannot be taken back. The reconciliation after a stalled MCP change holds providers only weakly and asks none that was closed.SettingsView.tsx: a refresh after an import takes an appearance value only when the import says it stored it, so an edit of a value that another provider changed is kept; every setter that has its own handler records its edit, so a late refresh keeps it.packages/types: thesettingsSaveResultmessage type.common.json(18 locales):errors.settings_save_failed, shown when a save is rolled back.Test Procedure
