The idea would be to have custom crafting recipes within the plugin so that it could be used as a crafting plugin too. This would be useful for unlocking locked crafting recipes or items without crafting recipes using items instead of RP. Dual choice to pay with RP or to craft with items could be implemented too. Perhaps an RP discount could be applied if the player has part of the crafting cost in inventory, but that last bit might be too complex to code.
