What Generation Features Do You Want Most?

I think it would be nice if we could get family members like grandparents, uncles, etc. to babysit while sims are away working. I would also like if family members could cook something or shower when visiting without being asked to leave. Generally, I would like more interactions between the generations, family gatherings and what not. Like maybe grandpa could send a birthday present through he mail if not invited to the birthday party, or maybe just call. Kids should be able to ride bikes with adults, or help with baking or gardening. They could do little things like decorate cakes or be able to place a limited number of seeds on the ground to germinate or water them every day. Also, we need better weddings.
