The items tab as it is now is fairly pointless. Originally, it was a quick way of representing the flow of items between recipes, but the current visualization is superior in virtually every way. It should probably be reworked into a list of total item-rates for each item. Those totals are not easily available elsewhere in the calculator, and it could even break down the item-rates in terms of belts, inserters, and/or logistic bots required to service that rate.
