It doesn't really bother me that much but I thought I'd point it out. The "highlighting" of the links at the top (Home, Inbox, Content..) is inconsistent. What I mean by highlighting is that when you click one of those links to go to that area, the box around the link is supposed to turn dark (I guess it's lowlighting). This works for Home, People, and Places.
But if I go to Inbox, the Home link is darkened.
And if I go to Content nothing is darkened.
