 - By default remember the last used level of backlight (even between reboots)
 - Smooth change of backlight levels (endless loop with customizable interval, default 1s)
 - Customizable slide gesture beginning on top left (default action is calculator with numpad activation and a requirement is end slide after atleast 0.3 of width and height)
+- Numpad is automatically disabled due inactivity (default 1 min)
 - Disabling Touchpad (e.g. Fn+special key) disables numpad aswell
 - Numlock state corresponds to the system numlock state (disabling sys numlock from e.g. external keyboard disables numpad aswell, reflect enabling sys numlock is optional)
 - Touchpad physical buttons (left, right and middle) are ignored when is numpad on
