I've been toying with a new forum header layout which has the goal of reducing the vertical size of the header. So far, I've managed to reduce it by about a third - which is a start, but not as much as I'd like. I did that mainly by conflating all three(!) navigation menus into one menu which uses dropdowns.

Anyway. Right now it's literally just me playing around. But feel free to look at it. Just switch your style over to "Dev Style".

I don't promise everything will work in that style.
