I have a couple setups where for the precision dropper i use a random item (sticks) to block of inventory slots in the dropper so i can export only 1 stack of a type of item. It would be nice to have either an option to only allow one slot to accept items or a different version of the dropper that only has one inventory slot.

Just found this today and wanted to add some support for it. Either a single slot precision dropper, or a UI option to lock out all but one slot would be uhmazing!
