A few thoughts for now -- I didn't get a chance to test this yet but the code is looking good!

It looks like the Spam one isn't quite centered vertically and needs to move down a bit -- probably because there's no description for it. I can't tell what we'd need to do to fix that just by looking, but I'd be happy to help debug if you'd like.
