Requested feature overview description.
What the title says. Separating tags by line based on their category in the edit tag box was a simpe but welcome change. It would be nice to have it in the thumbnails' hoverbox.

Why would it be useful?
It would make it easier for scripts to discern details about thumbnails.

What part(s) of the site page(s) are affected?
Thumbnails' hoverbox HTML code.

the path of least resistance may be to merge in the 'advanced tooltips' feature from danbooru, which looks like this:

Oh it does look nice. But I bet that would actually require a lot more work. It's a Javascript gimmick completely different from the common hoverbox.

i wouldn't assume a lot more work, since it's already implemented; should just be a matter of dealing with any dan/e6 incompatibilities which may or may not be present.

I removed the "enhanced" tooltip support from Danbooru because it fires off a network request every time the mouse moves over a post. It was a bit crazy. Making the template function locally would be my next course of action. But the common factor here is that if I can get away with never looking up the tag category for posts indexes, that's ideal. So I'm not promising anything right now.
