Trackpad Tuner

Trackpad Tuner is a GNOME touchpad tuner for pointer speed, acceleration,
and dragging.
Compare pointer movement using target, dragging, and text-selection exercises.
Save A/B drafts and test changes with a 30-second trial. Restore original
settings from a persistent backup, or reset the six tuning preferences to
GNOME defaults. Preferences apply to all connected touchpads. Supports GNOME
desktops; acceleration profile availability depends on the touchpad and
desktop session. After a crash, reopen the app or run --restore-pending to
restore an interrupted trial.
