When you open the “Relationships” table, family members appear at the top, followed by friends.
Sims with whom you have a romantic relationship but are not living together appear very low down. I would like them to appear right after family or have a system to sort relationships based on the criteria you choose: friends, colleagues, romantic partners.
I play multiple families in rotation and have many teens, every time I have to scroll to remember who has a relationship with whom 
, unfortunately I don’t have a very good memory
For example, the True Love of this teen appears very low down, below a list of friends.
The portrait isn’t there because sometimes it happens to me, I don’t know why, but I’ve played with him too and everything is fine. This ordering issue happens with everyone though.
