v1.1.6

What's Changed

Added

• Multi-instance application management: AppInstanceService detects and groups multiple running instances of the same app (open -n). Popover displays instance badges, collapsible instance rows with individual PID and memory stats, and individual or batch termination controls.
• Multi-instance restart: RestartService captures per-instance launch arguments (e.g. --user-data-dir) and relaunches each instance with its original arguments when restarting a multi-instance app.
• GUI integration test suite: grouped real WindowServer fixture tests and multi-instance lifecycle tests under a serialized GUIIntegrationTests suite (LastWindowQuitIntegrationTests, MultiInstanceIntegrationTests, AppInstanceTests, RobustnessTests).
• Space change detection: registered NSWorkspace.activeSpaceDidChangeNotification in LastWindowQuitService to track window state across Spaces and prevent false quits during Space switching.
• Quit when the last window closes: added an opt-in Automation setting ("Quit app when its last window closes") that force-quits regular apps after their last window closes via the red close button (x) or ⌘W, so they do not keep running in the background. Minimized windows, hidden apps, and windows on other Spaces are preserved. Excludes Finder, background daemons, music apps, and user exclusions.

Changed

• Helper process management: QuitService discovers nested helper processes via AppListService.runningProcessPaths() and ProcessTree.isDescendant; graceful quits wait for main processes to exit before cleaning up helpers, while force quits terminate all targets concurrently.
• App-group window tracking: LastWindowQuitService tracks apps by bundle path groups (appKey(for:)) instead of single PIDs, aggregating window counts across all member processes so multi-process apps (Electron, Telegram, Discord, Docker) only quit once all windows across all helpers close.
• Performance & battery efficiency: offloaded menu bar stats sampling to background tasks to keep the main runloop responsive, and dynamically throttled CpuUsageSampler to 10-second idle intervals when stats popovers are closed.
• Last-window quit optimization: cached WindowServer visible window queries (OSAllocatedUnfairLock, 0.5s max age) and web runtime detection paths (Electron, Chromium, Slack, Discord, Telegram, Docker), eliminating duplicate window list scans.
• Quit timer precision: replaced fixed 60-second polling timer with dynamic one-shot timer targeting the earliest due deadline, eliminating execution delay drift.
• Accessibility messaging timeout: enforced a 0.5-second timeout on accessibility queries in LastWindowQuitService to prevent UI thread hangs on unresponsive apps.
• Settings tab views now live in purpose-named files with shared controls separated, replacing clone-style type names.
• Removed unused duplicate and legacy PNG resources from the app bundle.

Removed

• Top processes section: removed the CPU and memory "Top Processes" list and background TopProcessSampler task from the stats detail popover, cutting unnecessary subprocess and kernel task walks.

Fixed

• Quit when the last window closes: force-quits instead of sending a graceful request that background apps could ignore. It now detects AppKit-retained closed windows while preserving minimized, hidden, and off-Space windows.
• Settings: quit-on-last-window option is strictly gated behind Accessibility permissions; revoking permission automatically disables the feature and resets configuration.
• Quit timer execution: pending quit timers are retried if an existing quit operation is in-flight instead of silently dropping scheduled quits.
• Web runtime app termination: properly handles helper process and window tracking for Electron and multi-process web apps during last-window quit.
• Settings reset now asks for confirmation before restoring preferences, shortcuts, and launch-at-login defaults.
• Reopening Settings, Welcome, Help, Exclude, or Update windows from the Dock restores a minimized window instead of leaving it hidden.
• Help: Finder & Trash opens the Advanced tab, shortcut copy says "Quit all apps", menu-bar stats help includes GPU, and "Report an Issue" opens the GitHub issue tracker.
• Stats detail panel: closing clears pending toast state.
• Settings: quit-on-last-window requests Accessibility only from Automation settings, never during app launch. Granted access shows a checkmark; Remove Access disables the option and opens the native revocation pane.
• Settings: Accessibility status now refreshes live while Automation settings remain open. The last-window toggle stays clickable and opens the grant flow when access is missing.
• Build: local app bundles now use a stable designated requirement instead of a changing CDHash identity, preserving macOS privacy grants across rebuilds.
• Automation: last-window close directly force-quits eligible apps. Minimized, hidden, and off-Space windows remain open and never trigger a quit.
• Testing: added a real WindowServer integration test that opens a fixture window, performs its close-button action, and verifies automatic force termination.
• Config: debounced saves can no longer overwrite a reset or a newer immediate save, and the memory-pressure threshold shown in Settings now matches the enforced value.
• Updates: "Later" keeps the verified staged update, and failed installs no longer leak staged files.
