I think there could be improvements in the editing environment. 
First, I'd like to see a separate button for freehand drawing and shapes like rectangles. I commonly will want to draw a white rectangle with white fill to hide something in the music and then I'll draw or stamp something over that area, but this requires many clicks that take too much rehearsal to control the freehand/box setting, line color setting, fill color setting, back and forth every time.

ANother nice feature may be to add optional white backgrounds for stamps. For example, our director tells us to change a dynamic from mf to mp...it would be great to just stamp a new 'mp' over the mf instead of needing to white out the area with a filled white box.

Mostly I'm looking to make edits as quickly as possible in a rehearsal setting to keep up with everybody else.

Ill list other suggestions on this thread as I think of them.
