This game needs a new item in shop that is a microchip. The point of the item is that you can attach it (via crafting bench) to another item and then that item will show up in the radar with a unique color (with the color upgrade). There have been countless times where I lost unique items because I was holding them and I fell over some mountain with my last save being way too far away. I would love to be able to go back and see where it is on the radar so I could get it back
