Yea, I really gotta agree, If you have enough output to produce 24 stacks of rods to go towards screws then why not have a full container? your screws will then move on into their own container that will get full, or be shifted into production of plates/rotors so you never have to shut down production. Thats the exact aim of the game. Productivity. Why limit yourself to only using say 1 storage container for 3 items if your output can fill three containers and still end up backing up the process? Ok, sure, 1 container is neater than 3, but, come one, this is a factory simulator, while there's a certain amount of neatness and order than *can* be bestowed on this, it's still a factory simulator. You're supposed to have massive walls full of storage containers of every known craftable product.
