So this is one of those things that bothers me... I can have a wishlist of items, but if I then purchase something off my wishlist, the item stays on my wishlist. I can see this making sense if I'm buying something I've wishlisted for someone else (because it's for the other person, not me), but if it's something for me, from my wishlist, it should disappear from my list. It's a bit annoying having to scroll through things and wondering if I already purchased it or not.

Related to this, we shouldn't be able to wishlist things we own.
