An option to preview items that you're about to buy before you actually buy them.
This is so players that buy things like swords and staffs purely for cosmetic reasons don't end up wasting a bunch gralats on an item that they deem "ugly" or "unappealing."
I've seen many people disappointed with an item solely because of the fact that it didn't look the way they expected compared to the way it looks on the item image and I think this would help players make sure they buy items they 100% will enjoy.
