Everything you need,
nothing you don't.

Quarter Snapping

Pin windows into any corner for a clean four-pane workspace layout.

Multi-Monitor

Press the same direction again to throw the window to the adjacent monitor.

DPI Aware

Per-monitor DPI scaling. Crisp and correct on mixed-resolution setups.

Lives quietly in your tray. Menu shows all bindings; clicks act on the last-focused window.
