Just an idea. It would be nice to be able to define a rhythmic pattern then in input mode just enter the notes without needing to change note values. This would come in handy if you were scoring something like Chopin’s F# Minor prelude, for example.
Also, I’m making a sort of chord & scale book and I have graphics of the keyboard with highlighted notes on every page. Each time I decide to change a master page layout I end up having to delete all the master page changes (which includes the graphics) then put the graphics back in again. I would love it if I could simply define where graphics should go in the master page editor, then choose which images to put on each page later in write mode.
… And since I’m here, text frame background colours would be good too.
