NexStage brings the macOS Stage Manager experience to your GNOME desktop. A sidebar of live window thumbnails sits at the screen edge, showing your open apps with real-time content previews. Click to focus, scroll to navigate, drag to reorder, right-click for options. Layouts: Arc carousel (signature curved look) or Vertical list. Position: left, right, or bottom. Modes: Raise-only (focus without minimizing) or Minimize-others (single-window stage, classic Stage Manager feel). Live thumbnails with real-time content. Active app highlighted, inactive cards lean for depth. Optional badges (window count per app), tooltips, close buttons. Multi-monitor: per-display or follow-focus. Reserve space (maximized windows avoid sidebar). Persistent or auto-hide. 4-tab Adw preferences window: Layout, Behavior, Animation, Shortcuts. Every detail configurable. Wayland & X11. Pure GJS/Clutter. No Electron, no npm. GPL-3.0+.
Note: Binary files aren't shown on the web site. To see all files, please download the extension zipfile.
