Make a new item filter that connects to the end of a pipe that only allows specific items through. We have an extractor, now why not a separate item that filters out items in the same pipe line? Like, let's say I have an extractor, whitelisted to only Diamonds, Emeralds, and Gold. Since they're all in the same pipe, I need a filter. Diamonds only in this chest, Emeralds in this one, and Gold in this one, rather than them all being put in one chest due to being unfiltered.

check other issues first before creating a new one
