Another VERY cool feature would be timers for your powermenu switches.

Like, tap and hold bluetooth switch long when it was set to off and a timeselector wheel pops up asking for how long it should be activated or on which time to automatic disable again.

For switches set to ON, the other way around. Bluetooth is on and when longpressed asks for how long to disable it befor automatic enabling again.

Makes also much sense for Flightmode in a whole, silence the phone, online/offline status and such
Maybe there could even be a circle displayed on the switches indicating running intervalls and show "progressed time" until next state change.
