This is just a detail but why not suggest an improvement.
When I want to go to a given Stack Exchange site I click on the "list bubble" icon top right which results in a menu with a list of sites. The list is long and therefore best navigated using the provided search field. Therefore, inevitably, I always enter a few letters of the desired site name which boils the list down to the handful of matching sites. However, even though the list is virtually unusable except through the search field, the search field is not in focus. I must click on it.
I suggest to give keyboard focus directly to the search field in the site list so that one can start typing right away (similar to the new Windows start menu).
An additional, even smaller improvement would be to give the "action focus" for the enter key to the top item in the matching site list. That way one can navigate to that site just by keystrokes after the initial menu click. This also follows the neat efficiency of the Windows Start menu (I didn't think I'd ever write that sentence ;-) ):
<Click menu>-c-m-d-<enter> opens the Console without intervening clicks or tab presses.
