An in game log would be nice, where the player could write down stuff they need to remember. You could write down an objective for the future such as trading with/conquering such and such place, or get x item. It wouldn't be a huge feature, and not everyone would use it, but it would be an easy place to store information (and it would be immersive) without having to write it down on paper or on a document online.
