One suggestion: I think a split pane ala mail.app would be an improvement over the current drawer. Use of a drawer implies to me, an optional part of the interface, but when working on a project, the file list is hardly option, in my opinion. Is there any here that opens and closes the drawer repeatedly to access their project listing? A drawer makes window resizing a two step operation -- you have to first position your window to accommodate your drawer before doing the resize.. Try it, you'll see what I mean. I think really, managing the use of space *inside* a window is much more natural than managing it outside.
