Ability to add notes to beats. For example, keeping track of bpm, struggling points within a beat, general notes to help with that beat, etc.
Additional user feedback: "Yes, I think my vision is probably being able to annotate a Beat. That could achieve a similar goal though, I feel. I tend to annotate worksheets or transcriptions for my students so being able to do the same within BN would be handy. If I need to do that currently, I export the PDF and annotate that. Annotations might include adding the count to a rhythm, practice BPM suggestion, reminders on a technical matter from a lesson etc."
