I loved how The Sims 2 did. I even used this feature to make newspaper stories in the neighborhood view.
I would also like to see the photo album in The Sims 4, because soon enough I run out of the room on the wall to put the pictures on, but I would also like to add new photos and reorganize the photos in the photo album this time. And it would also be great if they bring the memory system back from The Sims 3 (pictures of the game as a memory).
In the other word, I wish that the story mode (picture collection) of The Sims 2 and the memory system of The Sims 3 was back.
