I think an in-game notepad would be nice as recording things, such as codes for doors, would make more sense if the character did it. Obviously I can just open it outside of the game but this is assuming Anne is trying to remember which codes are for what or steps and things. Obviously it isn't that important but I believe it'd be a nice little QoL. An actual suggestion is Rim giving more help in exchange for doing something for her, I've read all the documents by the Alice so I can imagine what it'd be.
