Thread rows had two fixed shapes (the full card and, with #9417, a one-line compact row), so users couldn't choose which details a row shows or where. This adds a Thread list layout control in Settings → General (web and desktop). Pick Standard or Compact, or arrange row details into named custom layouts with up to three rows.

How it works

  • Contracts: ClientSettings gains sidebarThreadRowLayoutMode, sidebarThreadRowLayout, sidebarSavedThreadLayouts and sidebarActiveThreadLayoutId. These are validated schemas that reject duplicate details, duplicate IDs, and blank names.
  • Sidebar: Standard keeps main's card unchanged. Compact and custom layouts render through one shared ThreadRowLayout renderer in every section. The Settings preview and the real sidebar therefore can't drift apart.
  • Settings: the layout picker replaces feat(web): add compact thread list mode #9417's standalone "Compact thread list" switch, so there's one control. An existing sidebarCompactThreadRows: true still opens as the Compact preset. Editing a built-in creates a custom copy. Layouts support duplicate, rename (a rejected name shows an inline error), reset and delete, with keyboard and pointer editing. Preview my threads shows the layout on your actual sidebar. Every control stays disabled until settings hydrate, so a patch can't be built from defaults and overwrite saved layouts.
  • Docs: docs/user/thread-sidebar.md has a short "Custom thread layouts" section.

Web and desktop only. Mobile has its own native thread list and isn't affected. Client settings are per-client, so connection mode doesn't matter.

Stack

Stacked on #9417 (07ffd755c, rebased on current main). Land #9417 first. This branch is now one commit on top of it, rebuilt from the previous merge-heavy history.

Verification (head 07db5c9cf)

  • vp test run: web layout editor, saved layouts, layout settings (hydration gate), completed-time, timestamp, settings search, and sidebar logic tests passed (7 files / 231 tests). Contracts settings.test.ts passed (115). Desktop DesktopClientSettings.test.ts passed (11).
  • tsc --noEmit passed for packages/contracts, apps/web and apps/desktop. Targeted vp lint reported no errors; the only warnings are in existing Sidebar code. vp fmt --check passed.

Media

Recording · contact sheet

Layout editor contact sheet

This was recorded on 8c4fbcf. It shows Compact selected (36 px sidebar rows), a Standard duplicate edited by keyboard and pointer, and the edits surviving a reload. The row renderer and editor are unchanged since then. What changed is the rebase and dropping #9417's duplicate switch. A fresh capture on this head is still pending.

Approvability

Verdict: Not approved

Macroscope's review found this PR not approvable — This PR introduces a substantial saved-layout editor, persisted settings model, live sidebar preview, and new compact/custom thread rendering across multiple production components. It also adds product defaults for the new layout settings, so the scope and default behavior warrant human review.

Not approved because:

  • Per-PR cost limit exceeded (workspace setting). Approvability relies on correctness review in order to determine eligibility

📝 Walkthrough

Walkthrough

The PR adds configurable sidebar thread-row layouts. It adds layout contracts, saved-layout management, editor controls, sidebar rendering changes, settings integration, preview navigation, documentation, and test coverage.

Changes

Sidebar thread layout feature

Layer / File(s) Summary
Layout contracts and saved state
packages/contracts/src/settings.ts, packages/contracts/src/settings.test.ts, apps/web/src/components/settings/savedThreadLayouts.ts, apps/web/src/components/settings/savedThreadLayouts.test.ts, apps/desktop/src/settings/DesktopClientSettings.test.ts
Client settings now validate thread-row placements and saved layouts. Built-in and custom layouts support selection, creation, editing, renaming, duplication, and deletion.
Configurable row rendering and editing
apps/web/src/components/Sidebar.tsx, apps/web/src/components/ThreadRowLayout.tsx, apps/web/src/components/settings/ThreadRowLayoutEditor.tsx, apps/web/src/components/settings/ThreadRowLayoutEditor.logic.ts, apps/web/src/components/settings/ThreadRowLayoutEditor.logic.test.ts
Sidebar rows render standard, compact, or custom layouts. The editor supports drag-and-drop placement, hiding, reordering, keyboard controls, blank-space targets, and reset actions.
Settings integration and sidebar preview
apps/web/src/components/settings/ThreadRowLayoutSettings.tsx, apps/web/src/components/settings/SettingsPanels.tsx, apps/web/src/components/settings/ThreadListPreviewContext.tsx, apps/web/src/components/AppSidebarLayout.tsx, apps/web/src/components/settings/settingsSearch.ts, docs/user/thread-sidebar.md
Settings manage saved layouts, restore defaults, expose search entry points, and open a thread-list preview in the sidebar. Documentation describes custom layout controls and persistence.

Animation frame fixture cleanup

Layer / File(s) Summary
Animation frame cleanup
apps/web/src/components/files/fileEditorLanguageReadiness.test.ts
The fixture tracks pending animation frames, clears them during cleanup, and tests that cleared callbacks do not run after browser globals are restored.

Estimated code review effort: 5 (Critical) | ~120 minutes

Merge Risk: 🔵 Low · up to c03a5

Custom sidebar layouts may show an inconsistent timestamp for settled threads, causing misleading ordering or displayed time information. This is a bounded display-correctness issue that should be addressed before or shortly after merge.

Reuse sortableRootProps so the drag visibility sentinel applies to these rows.

sortableRootProps at lines 1389-1404 sets visibility: "hidden" when !sortable.isDragging && sortable.transform?.scaleY === 0. The comment there states that projected peers use scaleY as a visibility sentinel. This branch builds its own ref, style, and listeners and omits that sentinel, so a compact or custom row can stay visible during a drag where a standard row hides.

Use DEFAULT_UNIFIED_SETTINGS for the layout defaults.

DEFAULT_UNIFIED_SETTINGS is derived from the settings schema. The restore payload and dirty check duplicate those defaults. If a contract default changes, these paths can become stale.

Preserve settledTimeLabel for settled-row activity.

When variantAction === "unsettle" and a compact or custom layout includes activity, this branch can display threadTimeLabel(thread) instead of the settled timestamp. That can disagree with the settled-row sort order and the existing slim-row behavior. Handle settled rows before the generic ready and fallback cases.

Adds an off-by-default "Compact thread list" setting that renders active
and pinned sidebar threads as one-line rows while keeping their status,
PR, snooze and settle actions.

Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
Adds a Thread list layout control to Settings -> General. Users pick
Standard or Compact, or arrange row details into named custom layouts
with up to three rows, then preview them across their real sidebar.
Compact and custom rows share one renderer; Standard keeps the card.
The layout picker replaces the separate compact switch, and an earlier
compact preference still opens as the Compact preset.

Macroscope skipped reviewing this pull request. Per-PR cost limit exceeded (workspace setting).

Reviews on this PR have cost $27.11 so far. This review would add an estimated $3.61, bringing the total to $30.72 — above your per-PR limit of $30.00.

Tip

To get this pull request reviewed, you can:

  1. Comment @macroscope-app on this PR to request a manual review (monthly spend limits still apply).
  2. Exclude large or generated files from review by adding a pattern to your .macroscope/ignore.md — note that creating this file replaces Macroscope's built-in default ignores rather than extending them.
  3. Raise your cost limit in your workspace billing settings.
