MarketPress feature request - Wish List

I know this is the wrong place for a feature suggestion but I could swear I had entered this feature suggestion via uservoice but I can't find it anymore

I'd need something like amazon.com offers namely the wish list.
If possible let the user, if logged in, decide to make his wish list private or public.
If you consider adding this feature, why not make it better: if someone navigates to a wishlist, give him a cookie so if he buys a product coming from a wishlist, mark it as purchased on the wishlist.
The reason for this is to be able to use this feature i.e. for a wedding wish list - thus stopping people from making duplicate purchases?
