The current regions list is not obviously sorted and it isn't categorized. This makes comping a bit more awkward than perhaps it should be.
I would suggest that it was either:
-sorted alphabetically (so takes of the same track were grouped)
-actually in an expander widget for each track
-contextual to the track selected
It would also be nice to have a tag as good take feature (a bit like the favorites in the plugin manager?) so that if you have a good one, but you think you can do better it is easier to find.
I don't think this would be especially complex to implement, but could potentially improve workflow.
What do you think?
