Alright, an Array. To sum, an array is just a group of empty spaces that can be filled with items (most often the same type) in a selected area. Ex: Dave’s Hash feature is a complex array. Or, if you have a 2x2 array, you get Battleship.
Best part you just grab what item you need with no hassle, so John will have an easier time. But I don’t get the power button storage box.
