A native GTK4 + libadwaita desktop controller for a standing desk, built with Rust and Relm4.
The desk itself is driven by an ESP32 module. This desktop app never talks to the ESP32 directly — it's designed to speak to a small proxy server that relays commands to the desk and streams its state back. For now that link is mocked locally (see src/device.rs) so the UI has a realistic, animated desk to drive while the real proxy server is built out.
- Live desk visualization — a hand-drawn, animated side-view of the desk that rises and lowers smoothly in real time.
- Hold-to-move controls — press and hold to raise or lower, release to stop, just like the physical buttons on the desk.
- Sit / Stand presets for one-tap height changes.
- Routines — schedule automatic sit/stand transitions by time of day and day-of-week (every day, weekdays, or weekends), fully editable inline.
- Settings — proxy server address, connection status, and a cm/inch unit toggle.
- A splash screen that simulates the initial handshake with the proxy server.
