Even though Windowblinds are technically Visual Styles, I think labelling them as such is confusing and misleading in the Explore popup dialog.
Perhaps the 'Explore' link should be changed to 'Galleries' It took 3 of us 15 mins to figure out how to access the galleries.
The Mouse over on the forum categories looks fine with just the lighter blue mouseover but it jumping up a pixel and being underlined with dots on MO is not only overkill, but looks goofy.
Having a download count and a 'times viewed' count would be helpful to skinners.
I think the blue gradient on the sides of the site is overbearing and takes focus from the main elements, a solid more neutral, muted color would be better...
