Yeah, I noticed that, does not save preferences. :p And great to see the bug fixed! :D
Few other things I noticed - The Home, Blogs and Oekaki buttons don't work right now for me. Maybe you haven't gotten to it yet, I guess? And, apart from that, I don't see the "login" section anywhere on the main page if I log out and try to log in from this style. It shows register just fun but the text that says "Log in or register" doesn't link to log in page. At least, it didn't do yesterday. I'll check if it does today and report back.
Edit: Before I check, though, a question - hasn't Oekaki been canned? Why even make a button/link to it then? :p
Edit 2 - Weird. I could've sworn I had the style visible in the style selector at the bottom while I was logged out yesterday. Doesn't seem to be there today. Can't really check now, I guess.
Anyway, best style evar. I can't get enough of it and can't stress it enough.
