I think it would be nice to see if the skin is in a different resolution other than 800 x 600 (example - my AvicZ2 skin) so that someone specifically looking for a different resolution can easily find it (or people with 800 x 600 resolutions don't download a different resolution and have unexpected results.) This would also help people looking for tallscreen skins to filter through the mass of skins out there.
I know this thread is not designed to be a discussion thread, but I think it would be a good thing that would make it easier to find the information one may be looking for.
And by the way, thanks for taking this on. I was about two minutes away from pursuing this myself.
