[request] Copper Hopper

what i am suggesting is not just a reskinned hopper made with copper instead of iron.
Instead, it would be a version of hopper with a specific advantage for item sorting:

• only one item slot instead of five
  
• once an item is in, the amount never goes below 1 of that item unless the copperhopper gets powered
  
• when powered, copperhopper empties itself all at once into the storage of the next block, or if not attached to a storage block acts as a dropper for the entire stack at once
  

This means instead of having to build a bulky contraption of 2 hoppers, a comparitor, a repeater, a redstone torch, redstone dust and support blocks for each item you want sorted you just need one copperhopper, which uses much less space and requires fewer block updates.
Additionally, repeatedly powered it could be used for more controlled item transportation by injecting entire stacks directly into a bubble column in unattached/dropper mode.
