I would love it if someone could make a plugin that allows personal storage boxes. A "banker" could make a "bank" that would basically be like a secure box that players have to pay to access. The players could store things in it for a price but withdraw is free. Once a chest has been assignend to a player, no other player (except the banker) can access the chest. This way, servers can have a chest protection system that has a price. It would work great for servers that have open pvp and looting, but whose players still want to be able to store things.
