The leash only moved its reference when the head reached the leash's end, so after turning back it sat up to the leash off, and recentring meant overshooting with the head. The reference now eases toward the head's facing (POINTER_LEASH_RETURN, 0.2 s) and never lags more than the leash, so the cursor settles back to its place in the view once the head stops. The mouse can now move the cursor up to POINTER_FOLLOW_REACH (70 degrees) from the middle of the view, up from a fixed 40. Both are sliders on the Pointer page.

"""Frametop Input Settings: choose and map input devices for the universal 3D mouse.
|
|
|
|
A Kirigami (QML) app with a Python backend. It runs in the dev container and talks
|
|
to the input relay over its control socket (@frametop_relay):
|
|
- Devices: every USB/Bluetooth mouse and keyboard, a live activity light to
|
|
identify them, and a role for each (3D pointer, pass through, ignore).
|
|
- Buttons: press a button or key on a pointer device, then pick an action.
|
|
- Pointer: speed, dot size, distance and the rest, applied live.
|
|
- Bluetooth: paired devices, and re-applying the Bluetooth LE fixes after pairing.
|
|
Rules go to ~/.config/frametop-input.json and pointer settings to
|
|
~/.config/frametop.conf; then the relay (and through it the helper) reloads.
|
|
Launch with input-settings/ft-input-settings (host wrapper).
