Jeff, good presentation.

I think, the cell you have for "Time Loop / Editable chords" can be incorporated in general tools to minimize clutter even further. Loop can be defined in navigator (time line loop points). Loop options - into Transport button Loop. Loops on track level - right click on selection.

Editable chords... (editable chord track not to be confused with current C.Track) could be an optional strip, similar to wide navigator. An option of navigator bar.
