2) Press the 2 Shift buttons to enter MIDI mode
I actually want this but for the exact opposite reason -- I want to make it more difficult to enter MIDI Mode!
I'd imagine it being an option in the startup setup menu (when holding the first two select buttons) It'd be nice if there were a few options for functionality, IE make it easier as you've been asking, but then perhaps an option to disable it entirely -- I want to use my left shift button as a Control, my right shift button as Alt, so that way I could do, say, Control + Alt + Click (but this cannot be done right now as pressing left shift + right shift activates MIDI mode!)
Would love it if this were implemented!
