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. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
