Above is a mod that seeks to complete the item distribution functionality that allows us the hoppers, or hoppers, of Minecraft. With the new version of the hopper that this mod adds, we can now move items from an inventory up, and not just down, as was the case until now.
The operation of this new object, called Upper, works exactly like a hopper, only instead of taking items out of an inventory and moving them down, they will take them out and move them above themselves.
