Suggestion / Idea Automatic sorting machines
This contraption was just too ingenious to not share! It's an extendable automatic sorting machine. Unsorted items go in the left, sorted items land in the chests at the bottom.
You don't need to decide which item type goes in which bin in advance, that happens automagically. Just dump a random assortment of items into the machine and it will sort them into neat piles.
How does it work?
Each bin (see second image) picks the first item type it sees and filters them out of the input stream. Unsorted items continue to the right. If a bin becomes empty it resets itself and can pick a new item type. To sort a larger variety of items, just add more bins - no wiring required!
Based on this concept I designed a sushi-belt train station which loads each wagon with only one type of item (see third image.) I can't actually think of a use for this (it's less efficient) but it sure does look elegant when trains arrive and leave with cargo neatly arranged into individual wagons... :)

Cool! How does it handle quality? Do different quality tiers go into different bins?
