In my view this should be the default skin. Sorry to say that, but really the "new" default skin (replacing Blue3) is a step backwards in terms of aethestics in my personal opinion. And it's aesthetics that gives a lot of the first impression to something like MediaPortal.
On a more obscure note, my (let's be honest) rather odd MediaPortal system only has a projector as a display, no LCD panel or similar. And it's a 4:3 projector - still relatively common even though 4:3 LCD panels are really dying out. I just want to say that Avalon essentially works on a 4:3 display with some stretched images (e.g. CD album cover art is rectangular). Personally I can live with it, well I _am_ living with it!
