Copper Hopper

[AiDSl]

Describe the feature you have in mind.

Exposed hopper will stop collecting item from world,
Weathered hopper is like Exposed one but only first slot can be pull or push,other slot are disabled.
(disabled slot can still put item in and out manually and still contribute to comparator signal.)
Oxidized hopper is like Weathered one but totally stop pulling from top.

Exposed hopper will seal its top and only left a hole for item flow from container,
Weathered hopper`s gui will turn other 4 slot into red one.
Oxidized have fully sealed top

Does this solve a particular problem?

hopper in technical minecraft already do these things for reduce lag...
Exposed is like composter on top of hopper,
Weathered is like filter without need of putting sticks in other slot,
Oxidized is hopper pipe,only have 1 slot also make it less laggy when transporting.

I think it can also just be new type of hopper and only have 2~3 slot.
