One issue I've found is that menu_background.9.png being black, more often than not the menu text is unreadable. Every app that calls that menu for me (so far) has had black text, so to solve it I copied popup_top_bright.9 and renamed it. Still looks good and totally solved the problem so far. Just thought I'd mention it in case anyone else had the problem as well.
BTW: TOTALLY want the skinny blue bars. WANT.
