I still stand by my point. Although I understand that this isn't a way to measure usability; that Coffee House thing sounds good. =)
It does look prettier with group boxes, and with grayed out list as default, my eyes don't complain as much.

Just a question: I'm used to check boxes that enable widgets when checked, not vice verse (I think). Is it something to be considered? (I'm pretty sure it's just my memory playing tricks)

And finally: if there are only two appearance options, I would like to avoid tabs too.
