I would like to suggest making notes available in "layers," not unlike layers in Photshop or other image editing software. Currently, we have the option of setting the app to display or not display all notes/highlights. Here are a couple of usage scenarios.
1. I've studied Romans using the inductive method so there are many highlights and notes. But I attend a church where the pastor is beginning a series in Romans. I want to hide my inductive highlights and notes so I can focus on taking notes on the current sermon.
2. I've taken lots of notes on a particular passage and want to hide some of the notes (but not necessarily all of them) so I can look it from a different angle.
Make sense?
