Add Comment feature

Your idea

Add a feature that allows the user to add comments, sort of like the "Sticky" feature in Adobe Acrobat, or the comments in MS Word.

Here is a comment from Acrobat. You can move it around to any position on the file.

Problem to be solved

When working on a score, it is often useful to be able to make a "note to self" on some element to which one need to come back to at a later date. Some might use a regular pen and paper to manage those notes, but notes within the score are often a better solution, especially when working with multiple people.

In MU3.6, there is a plugin allowing that (Annotations), but (-) it isn't working in MU4.1 (due to the "unfinished" plugin API of 4.x), (-) it is a plugin, meaning it is not available when opening MU: the plugin must be manually launched at every start of MU.

Prior art

This feature is available in Sibelius:

Additional context

See Feature Request discussion on the forum Adding Comments.

No source files, tests, or entry points are identified. Start by reviewing the linked Adding Comments forum discussion and the Annotations plugin context, then determine the required editor and score-model scope; done means users can create and reposition persistent comments within a score.
