Here's mine -

1: We've said it so many times - there's no reason the mom can't work while having an infant. Especially since they work from the home. This should be doubly true for moms who work on the computers.

2: Earning coins takes so long it makes time travel very tempting. There needs to be more ways to earn coins.

3: Some items really should be cheaper. Especially a certain certificate.

4: It would be nice if praising/scolding actually did something about behavior. No matter what I try I can't get my people to understand that they need to be working, not walking around randomly. Especially when they only have 70 coins and are whining about being broke/needing repairs.
