**1. Removing an item from a champion, Without selling the champion**- I think once you have an item you should not be punished for passing it on, or for accidentally placing it on the wrong champion.
**2. undo a sell.**- Sometimes you regret a second too late after selling a champion.
**3. in game index-** I know there are many external ones, but a short list of champions and items would be very helpful in game.
**4. Customize the shop By Cost**- option to Prevent the store from offering a specific price.
