PAM!!!! WHOO HOO! Welcome back lady! Really, the Sims 4 ID is easier in many ways than Sims3. Just use a spreadsheet to keep track, or write your own strategy up and go for it. It's a bit more complicated, (but not any harder), if you do a rotational rivalry ID, but for me it got old having to switch around just when you got really into it. For me, Sims has to be fun and relaxing, not work and not too much strategy so an ID or one of the story challenges is my cuppa tea. I've missed you!
