Live X11 window thumbnail preview switcher, search & quick actions dialog

ScreenshotScreenshotScreenshot

A Linux X11 alternative to Alt-Tab Terminator. Independent open-source project, not affiliated
with or endorsed by NTWind Software.
Live thumbnail capture and global hotkeys require an X11 or XWayland session; native Wayland
windows cannot be captured or raised by external X11 clients.

FEATURES
• Live Window Preview List & Large Preview Pane: enumerates open X11 client windows via EWMH,
reads PID, WMCLASS, geometry, desktop index, and real /proc/<pid>/status VmRSS memory, and
captures live window thumbnails via QScreen.grabWindow (with XGetImage fallback).
• Quick Window Actions & Compact Switcher Overlay: search open windows, Activate, Minimize,
Pin On Top (
NETWMSTATEABOVE), Tile Left/Right, or Close Window, plus a compact Alt-Tab
style overlay triggered via Ctrl+Alt+Tab or Alt+grave global XGrabKey hotkeys.
• Layout Styles & Ignored Classes: switch between List + Large Preview and Thumbnail Card Grid,
filter by current desktop, configure capture refresh interval, and manage WM
CLASS ignore rules.
