I wouldn’t mind, but I think we should try to find a more universal solution for tag categories. As I said in the general thread, there are only so many different colors we can code with before it starts becoming hard to tell them apart. (And for color blind users, it’s already hard enough).
Once we have a more flexible basis for categorizing tags, we could start leveraging that to do crazy things like highlighting tags that share a category, or being able to put a single tag into more than one category*, and so on.
Kinda off topic, but food for thought?
*Relevancy here: A single category for ships is indeed useful, but imagine if there were no limit - you could make a category just for ships for a single character, or just lesbian ships, or even just ships between the mane 6, and one tag could belong to all of them!
