This is not a simple feature request (to my knowledge) but as I am starting to use SubTrees a lot more as they are a wonderful way to group and re-use logic I am finding that I keep making trivial mistakes as when I refactor my larger trees to take advantage of sub trees I forget to populate dynamic vars or static vars that the sub tree is dependant on.
So would it be possible to somehow show all the variables used within the sub tree, so you can tell before you start using what variables you need to instantiate for it to work?
(This is kinda like a step past my previous topic of showing dynamic vars with static vars)
