Changing the tins of food in your inventory to empty cans when they have been eaten could be quite an interesting and simple feature. It might be useful at those times where you wished you had a tin to throw, but you didn't bother picking junk up, or it could be used to follow people and track their movements. I know this isn't a huge suggestion, but its just a thought I had and I thought I'd share it. What are your thoughts? Also, this might have come up before, but I didn't see anything in the search.
