If they added Genies, what abilities would you want them to have?

I think it would be nice if there were degrees to how the wishes were fulfilled based on your relationship with the genie. If you have a good relationship, when you ask for money you get 5000 simoleons, but if you have a bad relationship you receive 50 simoleons. After they are released, you should be able to add them to your household and maybe they could do stuff instantly, like cooking, cleaning, gardening, fixing stuff, etc.
