Basically the plugin would do this Each time a chest is created the chest has an owner some how. If I plop the chest down it's my chest. From there any time someone adds or removes items from a chest that they did not plop down/create/own, it logs it. And it could create a log file that simply looks something like this: It would ignore people taking items from their own chests. This is ideal for servers who don't want to lock chests or use LWC but need something to catch people who are taking items from other players. In our case we have a private server and we're all friends but items are ending up missing. This way we aren't preventing theft, we're catching the thief so that we can ban them.
