Shop Wishlist - Shopping list

I had this idea while searching through the store and thinking of which champions and runes I need to purchase. I'm not sure is someone else has had this idea yet, I have yet to see anything about this. Here we go. I would like to express the idea of incorporating a wish list or shopping list tab that you can access while in the store. You would be able to add in runes or champions, the list would show what the item was and the pricing (maybe how far you are from that items amount). I feel like (at least for me) I spend a lot of time at the shop thinking about champions and having to write lists down on paper/computer of what I need to buy, this addition would make the shopping process easier and personal to the player. Like I said this may have been asked of Riot before, but I really like the idea and feel it would make my shopping experience more informative and easier to handle. Another small detail which I would like to see would be some numbers, this would include the amount of champions in certain categories and in the general shop, I often have to count all the champs to see how many I have left to buy. This isn't as big a deal as the list idea haha. Thanks!
