New Power page: - toggle for the firmware's 30 s keyboard backlight timeout - idle timeout for keyboard and lightbar, separately for AC and battery; predatord watches all input devices and restores the lighting on the next input - battery rules: dimmed keyboard brightness, keyboard off, lightbar off The rules only change what is sent to the hardware; the saved lighting settings stay untouched.
