Black Full Screen Possible? No PSD possibilty?

I love to evaluate pictures withouth any other frame than a black frame in full screen.
How to remove everything also the bottom bar and change to black rather than grey for a full screen?
 
Does the 2.0 version also show PSD (Photoshop files) ?
 
 

Preferences - Interface - Background gray level - will set background color.

Tab key hides all information panels

F key toggles full-screen mode

PSD files are not supported.

Thanks. Any Way to get rid of the "bottom bar", which is showing the rating etcetera in the full screen mode?
