I think it would be cool if we could get a codex section, just like we have with inventory, character sheets, dialogues, ect. This would add the information that we find with books. I know we can send those books or any items to camp but I know there are books you can't pick up but only read. That's where the codex is especially handy as we could read that information whenever we want. There are RPG's that have this in the game where you can always read up information regarding what you find in the game world.
