Lol I clicked on tags recently thinking it would do this exact same thing and it didn't so +1 xD
I noticed that when I select two tags at the same time, it only shows characters with BOTH tags.
But what if someone wants to mix tags and like, link character with tag1 OR tag2 ? eg I want to link a list of character I'd like drawn, I'd choose the "needs art" tag or the "favorite" tag, and both would be displayed at the same time so I'd need only one link. And instead of listing 4 characters to choose from people could just sélect their names tag and they would all be displayed at once.
Idk if that makes sense or if anyone else suggested this but I thought it would be pretty usefull !
EDIT : the + means "and", the - means "no", so it could ne another symbol which would be next to them.
+1 that'd be super useful! Not sure how the interface would look for that, but I'd love an OR operator.
