Aah! It's all blue!
Actually I'm just writing to say that the "keep me logged in" feature doesn't seem to be working right. I'm logged in now, but if I trim the address line down to just suddenly I'm logged out again. If I don't select "keep me logged in" I stay logged in for the browser session.
Other than that it looks nice. I like that the message I'm replying to appears at embedded text, not in a too-small box!
