DeeJanuzandClaude Opus 5.5 d439bc3f25 Frametop: a multi-screen desktop and universal 3D mouse for the Steam Frame
Several KDE Plasma screens floating in SteamVR, each a real monitor of any
resolution and shape, shown by our own compositor (ft-screens), with a
layout, wrist pinning, and visibility modes; a Bluetooth mouse that drives
all of SteamVR as a room-anchored 3D pointer (input relay, ft-pointer
helper, ft_pointer SteamVR driver); two settings apps; and Bluetooth LE
fixes. Installs on the headset with ./install.sh.

# Frame's copy is the one scripts/sync.sh keeps at ~/dev/frametop.
