@RIOT: Idea to Help Bring Back <Undo>

Hey I had this idea the other day, and everyone I've talked to about it so far was really excited about it. Please give it a read, and let me know if you think it would work. Looking for RED attention here so if any RIOTers see this I would love to have a discussion on the feature with you.

Would it work to make the sell button have dual functionality? For example, you buy an item, stay within the store and out of combat, and if you hit sell it gives you back full money for it, but if you leave platform or enter combat after you have bought the item, you would only get half the money back.

This seems to me like it would work, serving a dual purpose of simplifying store interface while also bringing back the feature many players love (in the bounds of the already present sell button's code). I do not know if that would fix the active item issue, but I would be happy to discuss and contribute to any methods of improving / resolving the issue.

Thanks for reading! Teys0
