1) The size of the bar numbers and chords in the Audio Edit window timeline area can't be changed (in either 2023 or 2024). The movable Audio Edit window is a good idea. You could narrow the chord sheet area and position the AEW on the right side over top of the mixer. Also, pressing the Audio Chord Wizard button puts the layout in a mode that has the AEW on the bottom of the Chord sheet.

2) To edit the audio on a RD track, you could first Copy the track to a Utility track. (right-click | Track actions | Copy/move track).

3) You could have one RD track that you have copied to Utility track 1. Re-generate the RD part and copy it to another Utility track. Find bars you like and copy them to Utility #1.
