Oh my, this is so good, thanks! If I may suggest: would it be possible to add the same "shift" feature that also allows to move the keys left and right?
Sometimes I come up with good patterns that I want to move just slightly, but doing that manually is really painful :D
EDIT: I just saw a twitter post where you show the left/right shift feature working on rythm patterns. THat's awesome! Do you think that feature will also work on instruments patterns? And will it also work on custom patterns, or just the default ones?
THanks for keeping on working on this already great tool :)
