+1! I’ve talked about this before, but seeing as a lot of my stories take place in the same universe, it would make my life so much easier to put characters in multiple folders as I sort them into stories and some are in many rather than just one. Split tabs does not help this as my characters almost never change AT ALL when in different stories, they look exactly the same.
Also, having characters fit into multiple folders works really well for a directory!! You can sort them into series, favourites (for if people want to draw them or offer on them, yes you can use tags for that but folders are much easier for me to visualise personally), universe, species (again, tags, but it’s still hard to visualise and find all the species tags without the characters on the same page).
With tags, if they want that to work, there should be a tag sorting option, because I have so many tags and it’s hard to find what I need. Like tag folders or something. You can make one for the species tags, one for availability tags, etc.
