App Mouse Button Remapper

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 WMCLASS Profiles: automatically detect the active X11
window WMCLASS 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.
