So what does it do? I can't find it anywhere on the website. It syncs Wallpapers through Dropbox? How is this different from me just chucking my Wallpapers folder on Dropbox anyway?
Also you could upload your entire wallpaper collection, to the site and then remove them from your collection, only keeping the wallpapers you want to see at any one time. It's useful if you've got a lot of wallpapers and a limited dropbox size.
