It would be maybe a nice improvement of editing if the transpose track/pattern functionality was midi mappable. Cool would be also a “transpose set to” midi map entry, so you can easily transpose the track/pattern using a knob on your midi remote.
May have been tidier and easy to keep track of if you had put your multiple related requests in the same thread.
Most, if not all, of what you posted is at least scriptable. More functions with native MIDI mappings options is pretty much always a good idea but sorry to say you might get a faster response formulating and making a request for a tool containing all you would like if you don’t feel you have the coding skills yourself.
