Virtual Screen Regions

A Linux X11 alternative to MaxTo. Independent open-source project, not affiliated with or
endorsed by Digital Creations AS. Window enumeration, maximize state interception, global hotkeys,
and region clamping operate on X11/EWMH (and XWayland); Wayland-native windows cannot be moved
or intercepted by external X11 clients.

FEATURES
• Region Splitter & Virtual Sub-Monitors: slice each RandR monitor horizontally or vertically via
an interactive recursive binary split tree with draggable splitters, persistent region layout,
and an active Maximize Interceptor Watcher polling NETWMSTATEMAXIMIZED_VERT/HORZ to clamp
maximized X11 windows inside their containing virtual sub-screen.
• Per-Region Maximize Mode & Live X11 Windows: inspect open X11 windows mapped to virtual region
IDs, maximize to region, cycle regions, span 2 adjacent regions, and toggle desktop region
border overlays.
• Preset Profiles & Global Hotkeys: save and load multi-monitor split tree presets (Ultrawide 21:9,
4K Quadrant, Dual-Display Split) and register XGrabKey shortcuts (Ctrl+Alt+M, directional
Ctrl+Alt+Left/Right/Up/Down).
