The ability to network the machines and the requester chest so, when you change what that machine is making it automatically changes what ingredients the requester chest is calling for. If this option is used then the requester chest menu changes. Then it asks how many of the item, you are building, do you want and multiplies the number of ingredients in each by that number.

Nice.

Many more things needs to be fixed before that: for example if an inserter holds an item he wants to put into the assembly just in the moment you change the recipe (the inserter will then block any production). And there are two or three more such issues.
