Just some things I’ve jotted down.
School and schoolwork
Is it possible to make it where parents can help their children with their homework, either by initiating it or their child asking for help.
Kids being home crafts or other forms of homework besides their books. And make it where they have three days to finish it or they receive and negative mark, which can affect their overall grade.
School bus is a nice touch! I’ve missed it. But I was wondering if it’s possible to ride along with your zoi to school? And even the option to have your adult zois drive and drop off their kids at school, and the option to pick them up as well.
More Clubs
For elementary aged kids they can have the Boy Scouts and Girl Scouts. And they can sale cookies, earn badges,
Food
Can you make the autonomy for zois to constantly want to make food less automatic. Like I will have a zoi make food for the family and either right after cooking it they will go to the fridge to either by a snack or quick meal, or they will start making a new dish. And other zois, instead of waiting for the cooking zoi to finish preparing the meal, they will go and make their own.
Drag and drop objects in live mode such as food. So after your zoi finished preparing a meal and sets it either on a table or counter, you can just move it to the center of the dining table.
Drinks! More drink options and also the ability to serve them along with a meal. Zois can have the option of making a group drink ( i.e. iced tea, lemonade, ice water, etc). Or zois could grab individual drinks from the fridge like soda pop, juice boxes, beer, etc. And adult zois having the option to make alcoholic drinks for meals as well.
I enjoy the set the table feature. But it could do with a bit more polishing in my very humble opinion. There could be an option to only set the table with tableware without food. And you can have three options: daily. Semi formal, and formal.
Please, please, please 
make the majority of dishes group servings. And not just that, but the options of two, four, six, eight, or party sized portions.
An easy bake oven for kids: they can make small treats such as cakes, brownies, muffins, and cupcakes. They can also have a smaller activity take where they can set it up in front of their home and sale their treats.
Instead of your zoi getting up to grab more food, if the plate is already on the table they can just reach and grab it. No need to more from their seat.
More Activities
Snowboarding
Surfing
Skiing
Skateboarding
Jet ski
Tennis
Kayaking
Soccer
Football: could actually football (on a smaller scale) be played same for soccer. And what I mean is like possibly two teams with four to six players each, and you can play/watch actual games. Both at the professional level and high school level. And the cheerleaders can have a sino off career like the pro nfl career.
Baseball: similar to the football, it can be an after school activity, a career as well. And a small playable sport of four to six players per team.
The same with basketball.
Water guns
Water balloons
Volley ball
Jewelry making (can become a business)
Glass blowing/pottery (can become a business)
Wine/beer making (can become a business)
Different types of bikes (mountain bike, race bike, electric bike) and a riding skill as well. And children can be taught how to ride a bike by their parents or alone. Their bikes come with training wheels, once they reach level one the training wheels come off.
