"Because we're discussing graphic interface changes and not functionality changes I wouldn't expect to see much difference in the Piano Roll, Notation or Chord Sheet windows other than look pretty stuff."

This is a wrong perception. Main idea behind users pushing for UI redo is mainly workflow / customization addressing known issues on the way. You have to view this holistically. Not one or the other.

Jim,
see attached image. This is how T.View looks with multiple choruses. I was actually able to generate 32 bars X 40 Got one giant snake of 1280 bars in T.View. And you can(!) partial regenerate segments of any tracks in any one of these 40 repeats. So not really sure what was the question about T.View in non-linear structure. Works like a charm.
