SUGGESTION - characters in multiple folders

This has definitely been suggested before, I think I may have suggested it once or twice, but out of every possible TH feature I feel like this is the one I need the most along with the links revamp. I’ve seen people use split tabs as a possible substitute, however when I have characters from multiple different stories their designs don’t often change? So I’d basically just have duplicate characters. I feel like this is a really important feature, and while I don’t expect it to happen any time soon, I still feel like it really needs to be done at some point!!
