TrimWM 0.9.0

New features

• Tabs layout (layout tabs, Option+T in the default configuration): every window of the workspace shares one frame like tabs in a browser. A Liquid Glass tab bar with app icons and window titles switches between them by click, focus, and focus next; move reorders them. Floating windows stay above the active tab.
  • tabs position top: a capsule tab bar above the window; the active tab is raised with an accent dot.
  • tabs position left: an icon rail that expands over the window to show titles on hover.
  • tabs size sets the bar's height or width, and tabs autohide true hides the bar until the tabs change or the pointer touches its screen edge.
  • With your own configuration, add bindsym $mod+t layout tabs to get the shortcut.
• Layout glyphs in the menu bar: each occupied workspace shows its number and a glyph for BSP, scrolling columns, tabs at the top or left, or WM-fullscreen, instead of T, N, and F.

Improvements

• Window titles are tracked live, so tabs follow title changes.
• The README now shows all three layouts.

Verification

• All 207 tests pass, including new tests for the tabs layout, tab bar geometry, menu-bar glyphs, configuration, and title events.
• The tab bar was checked live on macOS 27 at the top and on the left, with real Liquid Glass.
• The app is signed with Developer ID, uses the hardened runtime, and is notarized with a stapled ticket.
