With this add-on, the hoppers you choose will be able to move items much faster than normal.

How does it work?

To make hoppers faster you must upgrade them using a Gold Bar or a Diamond.
To do this place a Gold Bar or a Diamond in your hand while sneaking and interact with the hopper you choose, after this you will hear a sound and a Gold or Diamond border will be placed on the hopper.

The gold-enhanced hopper will be able to move items quickly one at a time.
And the diamond-enhanced hopper will move full stacks one at a time.

Once hoppers are upgraded, their upgrade items cannot be recovered even if you break the hopper.

Hoppers will not only quickly move items to another chest, they will also quickly extract items from the chest above.

The containers you see in the image below will be the only ones where the upgrades work for now.

Demonstration of how it works:

Warning: trying to manually place an item into a container that is receiving the same type of item you are trying to place may cause items to be deleted due to a Minecraft bug.
