KeepThatInventoryOpen
A simple client side mod that takes off inventory closing packets, so you can use the crafting grid as an additional storage space.
I don't know my version or loader
Background: When you open an inventory, the client does not send a packet to the server. However, when you close the inventory, a packet is sent. This behavior prevents you from using the crafting grid as a storage space.
Store Items in the Crafting Grid
KeepThatInventoryOpen is a client-side mod that prevents the client from sending the inventory close packet. This allows you to store items in the crafting grid and the mouse slot. But be aware that these items will get thrown out of the inventory if you rejoin the world/server.
Use at your own risk. Some servers may view this as an unfair advantage.
