Display of comments, highlights, etc

With comments/proofreading, is it possible to:

  • highlight areas of the score in different colors (for display on computer only)?
  • display comments in full in the score, rather than just in the sidebar, or separate comments into categories?
  • create custom proofreading categories?

Mostly what I’m looking for is the ability to leave notes for myself while working on things like the formal structure of a piece, areas of music I want to rewrite or edit, and so on, similar to comments I might leave in a word processor while writing a text document. Right now I mostly just leave shift-X text objects everywhere but then don’t always know exactly how much music they’re meant to apply to (and sometimes forget to remove them before exporting). Comments, for whatever reason, don’t seem to be visible in condensed scores.
