Another thing to consider is that some buttons are only relevant in certain states.
When the Maslow first starts up, retract all is relevant, but calibrate and extend all are not. After using extend all, take slack/calibrate become relevant, and retract all stops being relevant. After taking slack, give slack becomes relevant.
These don’t need to be on the screen in states where they aren’t relevant, so many of them could occupy the same space.
Calibrate could still be tucked away in setup, and all of the rest could live happily in the main menu above the DPad for immediate access.
