How about a track delay option in the Track Controller Settings?
For example, we could then advance or retard the timing of an individual track (or any selected portion) in real time in the context of the project. This would give a more organic and intuitive option to tweak timings, rather than using the global track delay feature or quantise. It would be good to be able to automate it as well.
I have a vague recollection that there was a similar function on the NED Synclavier back in the 1980s, whereby, with the twist of an encoder knob, you could slide the timing of tracks in real time against one another to achieve “groove” or “feel”.
