* feat(app): let the file panel close its tree rail
The file panel's tree rail was permanent on desktop — the changes panel
had a folder-tree toggle in its toolbar, the file toolbar had nothing, so
the rail was there whether you wanted it or not.
The changes panel's private DesktopTreeToggle becomes a shared
TreeRailToggle so both toolbars render the same affordance; that also
drops the treeToggleStyle prop threaded through ChangesToolbarProps,
which recomputed exactly what the component already built internally.
The i18n keys move out of workspace.git.diff into workspace.tree, since a
shared component reaching into the git namespace would rot.
The two rails keep independent flags — the file rail in panel-store, the
changes rail in useChangesPreferences — so closing one leaves the other
alone. FileTreeToggle wires itself to the store rather than taking a
callback: the bar renders several components below FilePanel, where the
rail actually lives.
Both rails also get narrower (320 -> 260 default, 200 -> 180 minimum).
The persist version bump resets treeRailWidth on purpose: nearly every
existing install carries the old 320 default, so without the reset the
narrower rail would only ever reach new users. Anyone who dragged their
rail to a deliberate custom width loses it once.
Note that MIN_CONTENT_WIDTH still clamps the rail to
`containerWidth - 240`, so in a narrow pane the new default never
applies — that floor, not the default, is what sets the width there.
* feat(app): make the side panel an empty workspace surface
The fixed, hideable side panel keeps supporting context beside an agent without seeding content. Pane-local choices stay local, while implicit supporting opens follow a persisted routing preference.
* test(app): exercise side panel policy through its capability boundary
The browser rail journey already covers the real tree-toggle behavior. Side-panel policy tests now pass their platform capability through the public boundary instead of replacing a production module.
* test(app): expect an empty side panel after upgrade
* test(app): expect an empty first split pane
* test(app): account for the empty side panel in split retention
* feat(app): make workspace panel tabs independent
Give explicit New actions fresh tab instances, keep panel state opaque to tab management, preserve File navigation context, and stabilize uncached File transitions.
* fix(app): preserve file conflicts during preview refresh
Keep the current preview mounted for same-target reads and conversions so the editor retains its conflict observation state. Clear retained previews only when the file target changes.
Preserve ambient placement for reconciliation and background opens while routing user-directed tab creation through the focused visible pane. Defer terminal reconciliation during creates so a push cannot preempt the intended pane placement.
* feat(command-center): add workspace file search
Use the existing workspace-aware fuzzy search so file lookup follows the file explorer's ignore and hidden-directory rules. Cmd/Ctrl+P opens a removable Files scope while the normal command center also includes file matches.
* fix(command-center): stabilize file search results
* fix(shortcuts): preserve project picker command
* fix(command-center): keep file results while searching
* feat(command-center): integrate the files scope into the search row
The scope was a 24px pill with 12px text sitting inside the 16px input line, so
it read as a badge dropped into the query rather than the scope of the search.
Make it a leading cell of the search row instead: folder icon, input-sized label,
and a hairline divider before the caret. It stretches to the row's cross size and
bleeds through the header padding with negative margins, so its height is driven
entirely by the input and the panel's own radius clips its corner. Toggling the
scope cannot resize the header, which the new spec pins.
* fix(command-center): restore the files scope as a chip
The previous commit turned the scope into a flush leading cell of the header. Put
the chip back: rounded, bordered, folder icon and 14px label, no divider.
It stretches to the row instead of carrying a height, so it is exactly as tall as
the input's line box and cannot resize the header.
* refactor(shortcuts): regroup and reorder the shortcut help sections
Panels was a junk drawer: the command center, file search, the shortcuts sheet
itself, new terminal, the sidebars, settings, focus mode and theme cycling. The
two shortcuts people reach for most, Cmd+K and Cmd+P, sat inside it below three
other sections. Navigation held both workspace and tab movement.
Sections are now General, Projects & Workspaces, Tabs & Panes, Layout, and Agent
Input. General leads with the command center and file search. Tab movement joins
Tabs & Panes, new terminal joins the tabs it creates, and Layout keeps only the
sidebar and focus toggles.
Row order is now data rather than a side effect of binding-definition order, so
the row someone opens the sheet to find sits at the top of its section. A test
fails when a new shortcut has no place in that order instead of letting it sink
to the bottom unnoticed.
* Keep file search failures in view
