Family relations and more

I agree that there need to be more official family tags. For instance, I'm playing a save right now where I have a sim who is a vampire, and his great-nephew (who also a vampire) has moved in with him. The game doesn't acknowledge that they're relatives anywhere but in the genealogy panel, though. Anywhere else, it acknowledges only that their roommates and friends.

Also, another thing that bugs me is that, whether or not a kid has met both biological parents, they have them both in their relationship panel from Toddler on up. What if I want the kid to never have known their biological father, whether he's alive or not? Also, the fathers who don't live with the mothers automatically invading the home when the kid is a Toddler. Maybe I want him to not know he has a kid, or be a deadbeat dad. Come on, game, ease up... :(
