A special hopper that collects items, mob drops and has an auto-eliminate feature for specific hostile mobs.
The hopper includes an easy to use GUI to filter mob types and select items you wish to collect.
Chunk hoppers are an efficient and lag-free alternative to complicated collection systems for:

Hostile mob farms (Creeper, spider, zombie, blaze, slime and skeleton).

Crop farms (Carrot, potato, wheat, seed, sugarcane and cactus).

Tree farms (All wood logs).
