What CAN be done to fix TS4?

I know this isn't high on everyone's list... but I would really like to see homeschooling! It's so irritating to me that I lose my child sims for 7 hours, 5 days a week, and they don't get skills or friends out of it! Then they come home, spend an hour and a half doing homework, and then only have time to eat, shower, pee, and go back to sleep so they have enough energy to not pass out at school the next day! With school, it is hard to complete aspirations and build relationships with their parents. I'm not asking for no school, I'm just asking for about 3 hours of assignments per weekday so that they can complete their aspirations, spend time with family and friends, and be more of a part of the gameplay.

Door locks. Even when you're not doing a challenge, door locks are convenient. For keeping kids out of the bedroom while parents are WooHooing, for example, which is awkward for everyone involved.

Also... Bed ownership. It's obnoxious when I send the parents in to bed and the kids are in the master suite.

Other things I think would be cool: illnesses and injuries (people get sick, it would be more realistic, but maybe have something in options to toggle them on and off for people who don't like them), hospital or doctor's office to visit for said ailments, maybe a restaurant, and PETS. But mostly the homeschooling.
