I would like to be able to create custom Note Indicators, such as being able to add letters (English, Hebrew, etc) to any of the existing icons (square, circle, star, triangle).
I believe you can basically already do that by using custom highlighting styles (and chose no note indicator). but this does not work for notes attached to a reference, it seems.
Edit: Actually, if you start with applying the highlight and then add the note text, it works for a reference in that particular Bible.
