Thinking along the lines of @kappatango suggestion for the resource base and displaying the number of items in that screen, an alternative would be to have the ability to ‘favourite’ specific items (i.e. the four items the resource base makes), then when you go to the Warehouse you don’t need to type in the item name in the search at the top or scroll tediously to find the item you want. If you have favourited them, they will always appear at the top of your inventory!
