In full screen mode, title bar disappears so it's hard to know what repo you're viewing

When you make a window full screen in Lion, the title bar disappears which also means you lose the document name. That's actually the primary way you can identify which repository you're viewing so it can be difficult at first glance to identify repositories in full screen mode.

This is a standard Lion feature and I've had the same problem in other apps. I don't believe there's a way to tell Lion to keep a title bar visible, so it probably means duplicating the identifying information somewhere, perhaps the footer. However, need to avoid wasting too much space on this since it's redundant in non-full screen modes.
