Well, where do we switch version? I'm still stuck with 1 for my entire wiki...

@Hackey5:


 * I don't want to search, and should I ever do, scrolling isn't much work - less than typing the search terms. Also, if i'm halfway the page, I'm already on the page I'm looking for.
 * If I want to access my profile, I'll just give the URL. Or I use the mousewheel to scroll, and you're up in a easier motion than moving the mouse to the top of the screen.
 * I never look for notifications halfway reading a page. I get them by E-Mail or because I choose to go look for them.

So no, it's no improvement at all, hence I disabled it the non-official way for myself.
