Can you add a permission that you can only give it to VIP for example?

Nothing is going to be done with this plugin (afaik) as the functionality is now part of the game

DISCONTINUED!This plugins functionality is part of the game.The game saves the crafting queue when a player disconnects or when the server restarts.The game puts the crafting materials back into the inventory of the player when they die.There is no need for this plugin anymore. Delete it.

yep, this plugin is no longer supported. it is part of the game
