Previously, Cmd+W on the last surface kept the workspace alive with a
replacement shell, unless the user toggled a hidden setting. This was
confusing—users expect Cmd+W to close the window when there's nothing
left.
Now Cmd+W (and the tab-strip X button) always close the workspace when
they close its last surface, and close the window when that was the last
workspace. Internal/programmatic closes (e.g. process exit, panel moves)
still spawn a replacement shell so the workspace stays alive.
Key changes:
- Track explicit user close gestures via markExplicitClose / onTabCloseRequest
- Remove the LastSurfaceCloseShortcutSettings toggle (now always-on)
- Use window.performClose for last-workspace window close
- Update tests to match the new behavior

* Add setting to hide Cmd-hold shortcut hints
* Bump bonsplit for Cmd-hold pane hint toggle
* Document tagged app link format in agent notes
* Disable Ctrl pane hints when hold-hints toggle is off
* Honor Ghostty background-opacity across all cmux chrome
Parse background-opacity from Ghostty config and propagate it through
the entire chrome pipeline: bonsplit tab bar (via RRGGBBAA hex),
browser panel/omnibar, titlebar, empty panel, and window background.
Decouple glass effect from sidebar blend mode — bgGlassEnabled now
defaults to false so opacity works independently. Add
GhosttyBackgroundTheme helper for consistent color+opacity resolution
across all UI surfaces.
Fixes https://github.com/manaflow-ai/cmux/issues/263
* Titlebar and chrome opacity matches terminal background-opacity
Use CALayer-level opacity for the titlebar background instead of SwiftUI
Color alpha, matching the terminal's Metal compositing path. Account for
the double alpha stacking in the terminal area (Bonsplit container bg +
Ghostty renderer) so the titlebar visually matches.
Also fix opacity-only config changes not triggering titlebar refresh on
Cmd+Shift+, reload.
Cmd+Shift+Enter toggles zoom on the focused pane, expanding it to fill
the workspace. Splitting or creating new tabs auto-unzooms. Zoom state
shown as icon in sidebar tab. Includes bonsplit zoom toggle support.
Closes https://github.com/manaflow-ai/cmux/issues/136
* Remove border below titlebar
Remove the 1px separator line overlay at the bottom of the custom
titlebar and its associated fakeTitlebarSeparatorColor computed property.
* Remove tab hover background in bonsplit
Update bonsplit submodule to remove the background fill on hovered
non-selected tabs.
* Restore titlebar border with system separator color, hover bg on all tabs, browser theme bg
- Add back 1px bottom border on titlebar using NSColor.separatorColor
(matches bonsplit tab separator color)
- Tab hover background now applies to all tabs including the selected one
- Browser address bar and under-page background now use Ghostty theme
background color instead of window background
The drop placeholder rendered in SwiftUI was hidden behind the
portal-hosted terminal surface. Add an AppKit overlay directly on
GhosttySurfaceScrollView driven by a new paneDropZone environment key
from Bonsplit so it renders above the Metal layer.

Three bonsplit commits (429af82, 2ff740d, b1948ab) adding the tab bar
+ button were lost when ad159da moved the submodule pointer to a
branch that forked before those commits. Merge origin/term-browser-icons
back into bonsplit main to restore them.
Adds a "+" button to the tab bar (next to split buttons) that shows a
dropdown menu with "New Terminal ⌘T" and "New Browser ⌘⇧L" options.
- Uses native NSButton + NSMenu so the icon matches the split buttons
- Menu appears below the button
- Routes tab creation through new didRequestNewTab delegate method

* Fix multi-workspace drag/drop, WebView click focus, and add regression tests
- Wire bonsplit isInteractive to workspace active state so inactive
workspace NSViews are hidden from AppKit event routing
- Add CmuxWebView.mouseDown notification for browser panel focus
tracking (AppKit delivers clicks to WKWebView, not SwiftUI overlays)
- Add multi-workspace focus regression test covering isHidden fix,
rapid workspace switching, and browser panel focus routing
* Bump version to 1.36.0
* Fix terminal keys (arrows, Ctrl+N/P) swallowed after opening browser
After a browser panel is shown, SwiftUI's internal focus system activates
and its _NSHostingView starts consuming arrow keys and other non-Command
key events via performKeyEquivalent, preventing them from reaching the
terminal's keyDown handler.
Fix: In the NSWindow performKeyEquivalent swizzle, when GhosttyNSView is
the first responder and the event has no Command modifier, route directly
to the terminal's performKeyEquivalent — bypassing SwiftUI's view hierarchy
walk entirely.
Also clear stale browserAddressBarFocusedPanelId when a terminal surface
has focus, preventing Cmd+N from being eaten by omnibar selection logic
after focus transitions away from a browser.
Adds DEBUG-only keyboard event ring buffer (KeyDebugLog) that dumps to
/tmp/cmux-key-debug.log for diagnosing future key routing issues.
* Fix split focus and Cmd+Shift+N swallowed after opening browser
Split focus: capture the source terminal's hostedView before bonsplit
mutates focusedPaneId, so focusPanel moves focus FROM the old pane
instead of from the new pane to itself. Also retry ensureFocus when the
new terminal's view has no window yet (matching the existing retry
pattern for isVisibleInUI).
Cmd+Shift+N: after WKWebView has been in the responder chain, SwiftUI's
internal focus system can intercept Command-key events in the content
view hierarchy (returning true) without firing the CommandGroup action
closure. Fix by dispatching Command-key events directly to NSApp.mainMenu
when the terminal is first responder, bypassing the broken SwiftUI path.
Also add Cmd+Shift+N to handleCustomShortcut so it's customizable and
doesn't depend on SwiftUI menu dispatch at all.
* Unified debug event log: merge key/mouse/focus into /tmp/cmux-debug.log
- Delete KeyDebugLog, MouseDebugLog, klog(), mlog() from AppDelegate
- Replace all klog/mlog calls with dlog() (provided by bonsplit)
- Remove debugLogCallback wiring from Workspace
- Add focus change logging: focus.panel, focus.firstResponder,
split.created, focus.moveFocus
- Add import Bonsplit where needed for dlog access
- Fix stale drag state on cancelled tab drags (bonsplit submodule)
* Fix split focus stolen by re-entrant becomeFirstResponder during reparenting
During programmatic splits (Cmd+D / Cmd+Shift+D), SwiftUI reparents the old
terminal view, which fires becomeFirstResponder → onFocus → focusPanel for the
OLD panel, stealing focus from the newly created pane.
Add programmaticFocusTargetPanelId guard to suppress re-entrant focusPanel
calls for non-target panels during split creation.
Also document the unified debug event log in CLAUDE.md.
* Clear stale title/favicon when browser navigation fails
When a page fails to load (e.g. connection refused), the tab was still
showing the previous page's title and favicon. Now didFailProvisionalNavigation
resets pageTitle to the failed URL and clears faviconPNGData.
* Fix Cmd+N swallowed by browser omnibar and improve split focus suppression
- Only Ctrl+N/P trigger omnibar navigation, not Cmd+N/P (Cmd+N should
always create new workspace regardless of address bar focus)
- Move split focus suppression from workspace-level guard to source:
suppress becomeFirstResponder side-effects (onFocus + ghostty_surface_set_focus)
directly on the old GhosttyNSView during reparenting, preventing both
model-level and libghostty-level focus divergence
- Remove programmaticFocusTargetPanelId from Workspace.focusPanel
* Fix omnibar hang, WebView white flash, drag-over-browser, and idle CPU spin
- Omnibar: first click selects all without entering NSTextView tracking loop;
subsequent clicks have 3s synthetic mouseUp safety net to prevent hang
- WebView: set underPageBackgroundColor to match window so new browsers don't
flash white before content loads
- Drag/drop: register custom UTType (com.splittabbar.tabtransfer) in Info.plist
so WKWebView doesn't intercept tab drags; override registerForDraggedTypes
on CmuxWebView as belt-and-suspenders
- CPU: fix infinite makeFirstResponder loop in controlTextDidEndEditing by
checking both the text field and its field editor (the actual first responder)
