I reall like the new invert branch feature, but I have issues with the UI:
* "invert inset" does not mean anything to me. "Inverted branch inset" would be better IMO, but still not perfect. Also the changing "(des)activate branch" could be a single "Active Branch" with on/off status.
* "invert inset" and "activate branch" do not belong together, since one is for the whole branch and the other is for only one inset (I understand this is the reason for the name above). Some separators should be changed.
* I do not like much the new unicode characters used for inverted insets, since they do not convey anything. I would instead keep the old ones, but make them give the state of the particular inset (active or not)
