1) It would be nice if there were an option to insert segments or remove segments, adding/removing space in the file as necessary. This way if I decide "part B should go at the end of the file", I can move parts C, D, E etc. over without having to select them all and drag them with the move tool. Likewise if I decide "part E should go between parts A and B".
2) If I resize a segment, matrix view doesn't shrink/expand to reflect this. Notation view does, though.
3) It would be nice if there were a way to select Dvorak's AOEUIDHTN instead of ASDFGHJKL to enter notes.
Thanks for your time,
