I would like to be able to replace page(s) in a song without losing the annotations made on that page.
In my case, we have a common repository of pdf's as a band where changes that affect all members are made.
My own information concerning a song (which guitar, which sound on the POD etc) is done as a text annotation. As it is now, when I replace the pdf (after conversion to png), I have to redo the annotation.
