AATWS (Advanced Alt‑Tab Window Switcher) enhances Alt + Tab in GNOME by adding search, filters, sorting, workspace and monitor switching, and flexible customization.
Alt + Tab in any operating system is used for quick switching between open application windows. But that simple key combination can always be upgraded to perform more useful actions.
With AATWS for the GNOME shell, the ordinary application switcher gains:
- Search – type to jump directly to a window.
- Filters – narrow the list by category, workspace, or other criteria.
- Sorting – arrange windows by most recent, title, size, etc.
- Workspace/monitor navigation – switch between virtual desktops or physical screens.

The app’s behavior can be modified in its settings, which I recommend reviewing immediately after installation.

There you can tweak almost any AATWS parameter, set animations, enable or disable features, and fine‑tune the experience to suit your workflow.
