Small feature idea. Wishlists for store?

Just an idea I had while browsing steam. Its hardly an original idea. Its hard to find any type of online store that doesnt have it. A wishlist to put all the skins you might want or champions. Maybe a notification for when you log in that an item on your wishlist is on sale? This could also tie into the gift giving after game. If someone is nice enough to gift you something, maybe they could look at your wishlist and unlock something off of it if they choose too. Would just be easier to keep all the skins I want under one file kinda thing.
