Introduction
A ~10MB native mouse enhancer for macOS — smooth scrolling, button & gesture mapping, a lightweight Logi Options+ replacement. Input-source automation included.
LinguaX has two co-equal core modules: mouse enhancement and automatic input-source switching. Marketing leads with the mouse — it makes any mouse feel smooth and powerful with tunable scrolling, side-button and gesture mapping, and per-app overrides, without drivers or background bloat. Input-source switching is the other half: a differentiating capability for multilingual and multi-app work. The two are independent, so you can use either on its own.
Mouse+ (Core Module)
Turn a basic mouse into a precise, configurable tool:
- Global smooth scrolling with tunable Min Step, Speed Gain, and Duration.
- Side-button and extended-button mapping (side buttons and virtual button slots).
- Gesture mapping by click, double click, long press, and drag direction.
- Per-app overrides so behavior follows the foreground app.

Input Source Automation (Core Module)
The other core module keeps your typing context aligned automatically:
- Automatic input switching per app.
- Domain-based switching inside browsers (Safari, Chrome, Edge, Brave, Opera; not Firefox).
- Clear priority: website domain rule > app rule > global default.
