I'm not sure exactly what you mean. If you want the whole app to be full screen, then use whatever OSX uses to maximize the Pr window. If you want a panel within the UI to be maximized, just press the `/~ key.
Thanks so much that's all very helpful. In regards to my full screen question I may be imagining it but I'm sure I heard you can bring the entire interface to full screen like you would with iPhoto or a web page etc.
Thanks again for such a quick response!

Are you asking how to make it show over the task bar?
