Shopping Wishlist

I would be nice to have a shopping wish list. I could add a few items from different shops I would still like to purchase but don't have the money for yet on this list. The list would be displayed somewhere on my personal profile and other users can view this and press the button "buy this as a present" for example. This way we can really buy presents for special occasions or birthdays for example, but items that a user still really desires without having to ask that someone what they want which takes away the surprise.
