Wishlist system

So I have been part of a few games, and not all of them use it, but some have what you call a wishlist system. Where you go to your games store, you do some window shopping and you add what you want to your wishlist.

The purpose of this is two things

1-To save it in ur wish list so you remember what you want to buy later when you do get the money

2-Maybe a friend or a kind stranger just feels like checking out your wish list and gets you something

I feel like this could easily be implemented into league, and while it's no ground breaking feature, it could be a nice convenient one to have.
