Actually, I was thinking about this...
What if you hit F twice to get to the Full Screen
In Full Screen Mode, panels are hidden. They can be accessed on the sides of the screen, or revealed by pressing Tab.
So if you press TAB while in full screen mode you'll see your panels, and then can right click outside the image's workspace to change the background from Black to a lighter gray if you prefer.
Of course Shift+F will take you back to the previous fullscreen mode where you can see the Menu Bar.
If you weren't aware of some of these settings then, I hope this helps!
Thank you for your reply, Pete,
actually I am aware of the possibilities you mentioned by pressing the F key for changing the view modes, changing background colors and revealing or hiding the panels via the shift key. But, I would have to repeat this procedure each and every time I open up PS because it always starts up with these standard settings. Lightroom on the other hand recognizes the last used settings/view options.
I used to have a little script I once found in the www which toggles full screen mode automatically when PS gets started. I just wanted to put that request, because of the changes on the UI that were already done within CS6 and I think that would be a welcome option to many of Mac users out there.
You're right, there is quite a bit of interest in the implementation of an OSX Lion-like fullscreen mode with Photoshop but it has its limitations.
Read Jeff T's post here for more information on the difficulties of implementing this at this time.
Thanks for the feedback!
