feat(web): optionally lay the chat and panels out as scrolling columns - #15949
2026-10-23 verification at 22b2243eef. Columns now integrate with main’s extracted chat header, panel, terminal drawers and action hooks; Appearance settings, surface reordering and single terminal ownership remain. Focused web logic and contracts tests, lint and formatting pass. Scoped types retain main-identical imported dependency/API diagnostics. Historical client media below predates this integration; current web/desktop acceptance and product approval remain open.
Earlier validation counts, review verdicts, CI status and captures below refer to their original revisions; older “current head” wording refers to those revisions. These focused local checks do not certify the whole suite.
Model: Claude Opus 5.5. Rebased onto current main with Claude Opus 5.5 on 2026-10-12.
Problem
The right panel shows one surface at a time. Reviewing an agent's work means flipping between Files, Diff, Terminal and Browser tabs and losing sight of the others. Even on a wide window, the conversation and its surfaces can't sit side by side as equals.
Change
Adds Settings → Appearance → Right panel layout: Tabs (default, unchanged) or Scrolling columns.
In scrolling columns there is no separate side panel. The chat and every open surface become columns on one horizontally scrolling strip, in the style of scrolling window managers like niri and PaperWM:
Layout: the chat is the first column. Each surface follows as its own column with a one-tab header, which keeps close, rename, mute and the tab menu. With panels open, every column takes half the strip, at least 26rem wide, and later columns scroll past the edge.
Navigation: selecting a surface scrolls its column into view, including one that is already selected. Pressing inside a column selects it, and the selected column gets a thin accent bar. Sideways swipes move the strip natively. Scroll areas with nothing to scroll sideways, such as the file tree or tab bars, pass sideways swipes on to it. Code viewers with long lines keep them.
Panel toggle: the right panel toggle shows or hides the surface columns, and the chat fills the width when they are hidden. Maximize is hidden in this mode.
Focus and painting: only the selected column takes keyboard focus and receives browser shortcuts. Terminals scrolled out of view stop painting, and scrolling never moves keyboard focus. Opening or using the terminal drawer under the chat scrolls the chat back into view. The drawer and panel terminals take separate focus requests.
Native views: a native browser view shows only while its whole column is in view, because it draws above the DOM and can't be clipped. The floating player shows only while the chat column is wholly in view. A column whose source is in the floating player shows a placeholder, so each native view has one owner.
Unchanged paths: narrow windows (sheet presentation), the Pull Requests page and mobile keep tabs.
Implementation:
One client-settings field in contracts.
RightPanelColumns wraps the chat column. When the layout is off it renders display: contents, so the chat keeps its place in the tree and switching layouts or opening the panel never remounts it.
ChatView renders each surface through one renderRightPanelSurface(surface, view). Tabs mode calls it with only the active surface, so the default path renders what it did before.
The inline, sheet and column tab bars share one props object.
RightPanelTabs gained showAddSurface, allSurfaces and titleBar for column headers.
Terminal panels gained autoFocus and offscreen switches, preview gained shortcutsEnabled, and device gained selected. Each defaults to its current behavior.
One small change reaches the tabs layout: a drawer focus request no longer also refocuses the panel terminal.
Scope and approval
New opt-in behavior, proposed in Ideas discussion #15944. The direction has no maintainer approval yet; feedback is welcome there or here. The default Tabs layout is unchanged.
Verification
Web client on a local dev server (vp run dev, isolated worktree state), Chromium at 1600×1000.
Video (real time, 50 s): switch to Scrolling columns in Settings, chat and Files side by side, select Files, swipe sideways to the terminals, run a command in Terminal 2, add Terminal 3 from the last column's +, swipe back to the chat, hide and show the panel columns, then switch back to Tabs. Full-quality MP4 (1600×1000, 1.2 MB)
Tabs (default, unchanged)
Scrolling columns
Terminal columns after swiping right, with output only in the selected column:
Checked in the browser (all observed passing):
No separate side panel. The chat and Files columns are 672px each, with terminals beyond.
Selecting a column moves the accent bar. Sideways wheels move the strip over the chat, the Files tree, a column header and a terminal. Vertical scrolling in the Files tree stays inside the tree.
Typed input reaches only the focused terminal column.
+ appears only in the last column, and adding a surface reveals its new column.
Swiping back keeps the composer focusable.
Hiding the panel lets the chat fill the width, and showing it again restores the columns.
Switching to Tabs restores the classic layout.
No console errors.
Focused tests:
vp test run packages/contracts/src/settings.test.ts (rightPanelLayout decode/default/reject) passes.
vp test run --project unit (apps/web) on ThreadTerminalDrawer, ChatView.logic, RightPanelTabs, composerScrollGesture, timelineScrollTarget and phoneTrackpad: 186 passed.
Typecheck (tsc --noEmit in apps/web) and vp lint on changed files are clean apart from existing warnings.
Not checked:
Desktop (Electron): not run. That leaves the following covered by source review only: native browser and device columns, full-visibility gating, the floating player, column-header window dragging, and per-column browser shortcuts.
Native browser pages: clicking inside one does not select its column, because guest-page input doesn't reach the DOM. Click its tab instead.
Terminals: a diagonal swipe over a terminal scrolls the terminal. Only a purely sideways swipe there moves the strip.
Snapping: small sideways nudges snap back to the nearest column edge; longer swipes move between columns.
Shell noise: the (eval):1: command not found: :4 line in a new terminal comes from the capture machine's shell profile, not from this change.
Independent review: GPT-6.1 Sol (high reasoning, read-only) through T3 delegated tasks. It ran six rounds on the original panel-columns version and five on the chat-in-strip redesign. Several more rounds on swipe handling led to replacing a JavaScript wheel router with one CSS overscroll rule. Every confirmed finding was fixed, and the final round of each reported no actionable findings.

Macroscope's review found this PR requires human approval — The change adds optional scrolling columns while retaining tabs as the default. New lint-suppression directives require human review under the configured approval requirements.

The right panel adds a tabs-or-columns preference. In columns mode, chat and open surfaces share a horizontally scrolling strip. Column visibility controls surface rendering, terminal painting and focus, preview shortcuts, device setup dialogs, and mini-player visibility.
The settings contract accepts tabs or columns and defaults to tabs. Appearance settings expose the choice and reset it to the default. Search, documentation, and contract tests include the setting.
Column layout and tab controls apps/web/src/components/RightPanelColumns.tsx, apps/web/src/components/RightPanelTabs.tsx, apps/web/src/components/ChatView.tsx, apps/web/src/components/chat/useRightPanelActions.ts
RightPanelColumns observes visibility and clipping, scrolls requested columns into view, and passes column state to renderers. RightPanelTabs supports embedded tab bars and shared surface actions. ChatView composes the layout and tracks reveal requests and column state.
Column state controls surface selection and visibility. Offscreen terminals remain mounted but stop painting, and focus can reveal their column. Preview shortcuts and device setup dialogs use their respective enabled, visible, or selected state.
Preview source matching and mini-player visibility apps/web/src/components/ChatView.logic.ts, apps/web/src/components/ChatView.logic.test.ts
Browser and device preview sources match panel surfaces by their identifiers. Mini-player visibility uses chat clipping and matching unclipped surfaces. Tests cover browser and device sources and clipped columns.

Suggested reviewers:juliusmarminge
Merge Risk: Low · previous review 163ee
Focus may return to a different control within a column. This is a bounded usability issue.
Security architecture risk: Low · up to d3b07
Scrolling columns keep multiple surfaces live at once. Existing permission checks remain in the inspected operation paths, but a background file column can handle the editor-opening shortcut and target a file other than the selected one. This is bounded target confusion, not a demonstrated privilege escalation.
Retained concerns
Low · security · inferred: Simultaneous file columns do not preserve selected-surface ownership of the editor-opening shortcut. Every eligible file column receives openInShortcutEnabled from panel-wide visibility and installs a global capture listener. A background column can therefore consume the user's shortcut and invoke the existing editor handoff for its own path. The base renderer mounted only the rendered surface. Existing environment permission checks limit authority, but do not validate the intended file target.
Security review details
Security Blast Radius
inferred — The demonstrated exposure is background file-target selection within the active thread's environment and existing editor-opening capabilities. Local execution remains permission-gated; remote mode hands an editor URL to the desktop bridge or browser. No cross-tenant access, additional credential authority, or arbitrary code execution was established.
Security Findings and Attack Paths
inferred — With multiple eligible file columns mounted, a genuine favorite-editor keystroke can be consumed by a background file's window listener. That listener uses its own retained path and prevents later listeners from acting. This weakens target-specific user intent; it does not establish that untrusted content can independently generate a privileged action.
Trust Boundaries and Controls
observed — Several controls explicitly account for simultaneous surfaces: preview shortcuts require active and unclipped state, device setup dialogs require selected state, and terminal operations retain their environment permission checks. These controls limit broader background activation, but the file editor shortcut does not use the equivalent selection gate.

Explanation
The title "feat(web): optionally lay the chat and panels out as scrolling columns" matches the main change: an opt-in Right panel layout setting that shows chat and surfaces as horizontally scrolling columns. It is a conventional commit title in plain language and is specific enough for a teammate scanning history.
Full details: Description check
Explanation
The description follows the template's sections (Problem, Change, Scope and approval, Verification) and includes a Model line, so the structure is complete. It explains the problem, the change, the verification steps with browser checks, and the unchecked areas. Scope and approval is weak: the author states no maintainer approval exists yet, and the template requires approval for broader workflow changes. The verification also relies on screenshots and video for UI changes, which is adequate. The description is mostly complete, but the approval requirement is unresolved and the earlier revision notes add noise.
Resolution
Not required for PASS. For merge readiness, the Scope and approval section still needs a maintainer-approved direction (the description links discussion #15944 but states no approval exists). The description should also state clearly which verification applies to the current head, since older validation results refer to earlier revisions.

Scrolling columns no longer keep a separate side panel. The chat is the
first column of one horizontally scrolling strip, followed by a column per
open surface, each with its own one-tab header. Narrow windows keep the
tabs sheet.
- The chat column keeps its place in the tree, so switching layouts or
opening the panel does not remount it.
- The chat's terminal drawer pauses painting while the chat is scrolled
away, and drawer actions scroll the chat back into view. The drawer and
panel terminals take separate focus requests.
- The floating player shows only while the chat is wholly in view.
- Column headers keep bulk close actions and desktop window dragging.

In the scrolling columns layout the floating browser or device player hid
whenever its source was the selected surface, even after that column had
scrolled out of view, leaving the source shown nowhere. It now gives way
only to a column that is wholly in view and shows the same source.

The scrolling-columns proposal in Ideas #15944 is the right place to discuss this direction; no duplicate report is needed. The current PR says approval is pending, and the discussion currently contains no explicit maintainer approval of the direction and scope.
This changes the workspace layout, navigation and visibility across chat and the panel surfaces. Under CONTRIBUTING’s prior-approval rule, that new workflow needs explicit maintainer approval before it is eligible for deeper review. An opt-in setting and linked proposal alone do not provide that approval. The related issue #1741 describes the existing chat/terminal side-by-side capability; it does not approve this broader layout.
Please continue the direction and scope discussion in #15944. This PR may be closed under the contribution policy while approval is absent, and can be reconsidered after explicit maintainer approval. The usability report and supplied UI evidence remain useful. This comment does not claim the PR has been closed.
this needs prior approval under establish the problem and scope first. RightPanelColumns replaces the single active panel with a horizontally scrolling strip containing chat and multiple surfaces, with new selection, visibility and focus behavior. that is a new workspace workflow even though tabs remain the default. the scope section says approval is absent, and discussion #15944 contains no explicit maintainer approval. the report about losing context while switching panels remains useful. obtain explicit maintainer approval of the direction and scope in that discussion, then request reconsideration with verification for the accepted scope.

Wrap handleUnclippedColumnSurfacesChange with useStableCallback.
This handler leaves ChatView as the onUnclippedSurfacesChange prop. RightPanelColumns lists that prop as a dependency of an effect. The repository rule for ChatView requires useStableCallback on handlers that leave the component. A new function identity on each render can rerun that effect, and each run calls setUnclippedColumnSurfaceIds(new Set(ids)).
As per coding guidelines: "In large, long-lived components such as ChatView and ChatComposer, write handlers as plain functions and wrap them with useStableCallback only where they leave the component: props, hook dependency arrays, and effect or memo bodies."

3349-3350: Minor · Functional Correctness · Quick win
Use a column-specific workspace focus key.
activeSurfaceId is the selected tab, not the owning column. In columns mode, inactive columns receive the same selected ID, so their PreviewPanelShell instances share one focus-history entry. Pass each column’s own surface identity to workspaceFocusKey, while keeping activeSurfaceId for tab selection. This prevents focus restoration from falling back to a different control when columns share a key.

reproduced the missing layout on github main 15fe283272, then checked the exact contributor head 6f8ffeb6 in the running linux web app. used repo playwright with google chrome, isolated app state, an app-created project pointing at a real git checkout, and real codex gpt-6.1-sol turns. the same conversation is shown before and after below.
fixed six regressions on the existing head branch, now 6d54b02ab7bbdd1eeda51f8af513339142a352c7: missing side-chat creation, narrow-screen columns despite sheet fallback, sheet maximize doing nothing, column reordering, keyboard column ownership, and f6 getting stuck between repeated panel regions. no force push.
verified appearance settings switching between tabs and scrolling columns; horizontal wheel scrolling; file browsing; independent terminal inputs and the terminal drawer; drag reordering; panel hide/reopen; light/dark; narrow fallback and maximize; and a real browser loading example.com, floating over chat, and returning to its column. parent and side-chat sol turns completed through the app, including approving a real side-chat context-read request. after the final restart, keyboard focus selected the correct terminal column, keyboard splitting affected that column, and f6 cycled sidebar → conversation → composer → panel → sidebar. no browser runtime errors observed.

Model: Claude Opus 5.5. Rebased onto current main with Claude Opus 5.5 on 2026-10-12.
Problem
The right panel shows one surface at a time. Reviewing an agent's work means flipping between Files, Diff, Terminal and Browser tabs and losing sight of the others. Even on a wide window, the conversation and its surfaces can't sit side by side as equals.
Change
Adds Settings → Appearance → Right panel layout: Tabs (default, unchanged) or Scrolling columns.
In scrolling columns there is no separate side panel. The chat and every open surface become columns on one horizontally scrolling strip, in the style of scrolling window managers like niri and PaperWM:
Implementation:
RightPanelColumnswraps the chat column. When the layout is off it rendersdisplay: contents, so the chat keeps its place in the tree and switching layouts or opening the panel never remounts it.renderRightPanelSurface(surface, view).

Each defaults to its current behavior.One small change reaches the tabs layout: a drawer focus request no longer also refocuses the panel terminal.
Scope and approval
New opt-in behavior, proposed in Ideas discussion #15944. The direction has no maintainer approval yet; feedback is welcome there or here. The default Tabs layout is unchanged.
Verification
