As the GM, I have a search function in the journal tab of my game, and a tag system. For example, I can type "ally" and see who my players have befriended during the campaign. My players, however, do not have this option. Instead, they have to click through folders and search manually. Having a tag and search function is partially meaningless if only the GM benefits from it. My players should be able to search for things they've been shown, too.
