In settings, add a note color for what a key switch would be. In other words, if the user knows that keys below, let's say, C2 and below are going to be key switches, maybe use purple as that color.. etc. (If that is already set up in settings, ignore this one)
For a selected track that you are forwarding to, allow note re-use, but, also color code the notes maybe with the track color it is going to. If the note is going to multi tracks, use a multi track note color.
Add a rule for all notes for a quick all note kind of add.. For me, I'll probably use the note range, but, would probably run across needing everything at some point.
All in all, very cool stuff. It now allows me to edit even faster as I can now work on one track. Like this:
