The search for viewing skins uploaded by others is a little broken. I was looking for Adventure Time skins and each time I searched and clicked to go to the next page, what I had searched seemed to have cleared and was showing the most recent uploads again, instead page two of the search results. The import skin to edit option also just doesn't work for me, even if the skin is displayed and every button works, It just doesn't bring it to the editing screen.
That's a little bothersome, but it might just be my laptop.
Other than the search and import skin option it's the best skin editor out there.
