I similarly noticed the lack of Control-Shift-F ability to exit full screen. Also, there seems to be a bug where occasionally when I complete a task in full screen mode, it kind of half exits full screen mode. By this I mean that the menu bar comes back, the application moves back to my primary desktop space, and the borders/edges of OmniFocus become visible. I do not, however, get back the close/minimize/restore buttons, so I have to manually go to View > Exit Full Screen to use my other apps on the main desktop. Not a huge deal, but a little irritating.

Edit: I quit and reopened the application, which seems to solve this at least temporarily. I guess the point is that Full Screen Mode doesn't seem fully baked in this version.
