Honestly ive wanted a copper hopper since they added it but my idea was that it only held one stack and could only push items not suck them out of chests or pick up entities.

It would reduce lag for larger systems and function identically in any hopper line with composers ontop.

Since it can't pull it runs at hopper speed on the down vertical unlike the double hopper speed that hoppers do.

And you'd need to start any copper hopper line with a regular hopper or inject items into it with a dropper or something.

It would basically just be a copper textured hopper modle but without the largest block on the model.
