I was very confused for a minute when I saw this post with that name. I thought some old thread got dig up or something.
As for the question, probably not. We basically use the simplest Booru format and don’t really have the capability to change things around much, I don’t know the specifics myself but it’s something like that.
I don’t think there’s much need for such a small change. I find it more convenient to have blacklisted tags collapsed until you want to tweak them, though that’s mainly because I have a lot of blacklists.
Could you expand upon what exactly you want and why you want it so I may better understand?
