The way this plugin stores data is fundamentally different from MultiVerse-Inventories. Like MV-I, this plugin saves data in a .json format, but that is where the similarities end. Not only does this save your inventory, it saves your stats as well! This includes things like active potion effects, exp, level, economy balance, and more. These all can be configured on a per-item basis, should you not want all of these saved. See the Configuration section below for these. All commands can be seen ingame with the '/pwi help' command.
