Optional/addituonal notes in fretboard diagrams
Has there been any discussion of allowing multiple notes per string in fretboard diagrams? I see one mention in passing but perhaps I'm overlooking something. In some situations, it would be helpful to show a chord's modifier note, such as a trill or grace note. In others it would be good to use a diagram to show a series of scale note positions that would support a particular harmony. The additional notes might appear as solid black or gray dots, or as hollow circles. My preferred interface would be a toggle inspector property to "allow multiple notes per string" and the ability to choose or rotate each dot's dot appearance as solid, gray, or hollow. The main use for this would be in teaching material, though I can imagine situations where a normal score might also benefit. Sorry if I've missed a discussion on this.
