Item Vortex

I think there should be an item called the "Item Vortex". You could link it to a container and could use it to temporarily turn an inventory slot into a vortex. You could place items in that slot to teleport them into the selected container. This would be useful if you're running out of space in your inventory, but are worried that the items on the ground may despawn by the time you get back from your chest. It would be a late-game item.
