Seems wasteful (cpu/energy wise) to have it redrawing constantly when not in use. I wonder if maybe an option could be added if it’s sitting at the same (non home) screen for X time, back it out to the home menu, or suspend updates till a user input occurs?
e.g. options something like this:
Return to home screen after (5|10|30|60) minutes of no user input.
Suspend display updates after (5|10|30|60) minutes of no user input. Any user input will resume display updates.
