put a "search repositories" box on the front page

Coming to the BitBucket front page for the first time, it's quite hard to see how to search for the repository you want. There are multiple text input boxes, but they are all for login and/or OpenID input. It's not that obvious that you must click on the "repositories" link.

A prominent serach box entitled "Find repository" (or similar) would help a lot.
