Hi Mike,

The piano staff in the annotations is a nice option. I'd like to suggest/request that you can adjust that with an option to choose just a single staff (treble or bass) and equally important to have a translucency for it similar to the highlighter so you can cover up existing staffs and write notes in it.

And additionally please provide a single measure staff (adjustable in size of course) with the same feature to cover up and annotate single measures in the same way.

Thanks.
