totally agreed! i’m planning on doing a small update in the next week or two which will allow folks to assign the remaining keys on the main page to any one of a batch of actions – so like, if you don’t have an arc (which the four keys under each bank control), you can just reassign one of them to something like toggling MIDI output, or using those to pull up pages on norns without clicking around, or tap tempo, etc 
i’ll keep this one in the log for assignable actions! thanks for the ping!
tho for now, you could map a MIDI controller under PARAMS > pad to note setup to quickly toggle bank x MIDI output? on and off
