Track versions don’t let you visually compare the data. For me, they are almost useless. Perhaps they’ll save the near-instantaneous operation of duplicating the MIDI track, alt+dragging the part down, and hitting ‘M’. Also keeping my session tidier.
If you could visualize the parts, like as playlists, and have them play back as lanes, that would be very handy.
By the way, these stupid dropdown menus eat up about 1/4" of name real-estate on my tracks. Pardon my language, but what tf are they thinking here?
