thanks for sharing this.

Adding support for full screen toggling is real easy (and cool, too), 
so I'll add that feature to the set of core features.

Regarding your Front Row issue: if you enter the menu from inside 
Front Row, is the Front Row behaviour the currently active?

And, just to be sure, if you manually activate the iTunes behaviour 
when inside Front Row, does skipping back and forth still not work?

If I understand you correctly, you're trying to use the fullscreen 
iTunes visualizer while also in Front Row. I've never tried to do 
that and I'm thus not sure how and whether Front Row can handle this 
correctly.

Best regards, 
Felix
