Besides the many questions/complaints below about appearance and style, I'm really just not seeing how this is in any way a streamlining of the old top bar. It seems like everything takes at least 1 and sometimes 2 extra clicks to get to.
Personally, I think it looks really nice (except the envelope/inbox image does not look like an envelope so much as the back of a station wagon), but it's just really inconvenient to use.
In particular, needing to click "StackExchange" to get to "Chat" and "Log out" really bugs me.
Anyone in agreement on this?
