Not sure if this helps but I keep the staff view open at the top of the window and use the piano roll for editing. Moving stuff is easy in PRV.
I was thinking about trying that. At least that would give one a visual reference to the notation as a double-check while working in MIDI. OTOH, they highlights how weak the note editing is. It seems to me the goal should be to have those two windows open, and to be able to operate on EITHER notes or MIDI, with comparable productivity and consistent gestures in either case.
I realize we may be beating a dead horse, but I just wanted to point out some examples of basic requirements that go well beyond simply fixing the bugs and adding triplet support, without creating notation system of the scope of Finale or Sibelius.
IMHO, we don't need more plug-ins. The DAW itself is extremely robust. The concentration should be on ease of use and productivity.
