All make sense if I think about them, but I have to really pause and think about them and the result is I don’t use them and they just jumble up the screen. I know this is a UI issue but it’s been bugging me the entire time and I think is basically unusable. So, my suggestion, which I’ve thought about for approx 30 seconds, is to replace the collapse and expand all text with ▲ and ▼; and for expanding or collapsing in a particular level of the tree, something else, probably just a 🌲 for now.
