I think the Chords Timeline work great, but I would like to see perhaps, text to show 1 verse, 2,verse, etc... as well as where you have some kind of action, like Fills, Push/Hold, etc...
Maybe R1, R2, R3 for the Repeat signs, and a "F", "P", "H" and for more than 1 action in a bar "$" (used a dollar sign, could be whatever works best).

I can easily zero in on a bar in my song, if needed.
