Some type of storage system that works similar to a Computer. For example. You have Hard Drives which add 64 slots these connect to the Motherboard which then needs to be connected to the Terminal Interface. If there were lots of Hard Drive slots then you could have all your storage in one place and then some how have your items from all you different machines put into the hard drives. Also if you could search for items or just scroll through them you would be able to get to you items a lot quicker. Then if there was a way to connect the Computer to the Crafting station and you could select the item you want to craft then you could click on it and the Computer would search to see if you had those materials available and if they are, then they will be put in to be crafted. Having a system like this would be very Satisfactory. :)
