It would be really nice if there was an in game journal that acted as a wiki by automatically recorded things that you discover in game. The best example of this is when you gift someone an item, in the journal it could record whether or not the person liked it. Same could go for recording which fish you caught in which location and season and which foragable items are in which season, as well as any acquirable item in the game. It could be similar to how the unlearned cooking recipes are shown currently. You would have to "discover" the item first for it to go into your journal, so it won't be cheating by telling you everything.
