A lightweight Linux X11 alternative to X-Mouse Button Control for per-application mouse button, wheel, and chord remapping across multiple Shift Layers. Independent open-source project, not affiliated with, sponsored by, or endorsed by Highresolution Enterprises or X-Mouse Button Control. Uses standard X11 window class detection, pointer polling, passive XGrabButton remapping, XTest input dispatch, and EWMH window actions on X11; Wayland-native sessions restrict external X11 pointer remapping.

FEATURES

• Per-Application WM_CLASS Profiles: automatically detect the active X11 window WM_CLASS and apply custom mappings for browsers, code editors, file managers, or any window picked with the interactive crosshair tool.
• 4 Shift Layers & Button Chords: map Middle (Btn 2), Side Back (Btn 8), Side Forward (Btn 9), Wheel Up/Down, and multi-button chords across four switchable layers via hotkeys, modifier hold, or button actions.
• Real X11 & EWMH Actions: emit key chords, insert text snippets, send scroll steps, or trigger minimize, maximize, close, and always-on-top.
• Live Monitor & JSON Presets: inspect live pointer coordinates, held buttons, open X11 windows, audit firing logs, import/export JSON profiles, and switch between English and Vietnamese interfaces.
