I may be submitting this twice and apologize. I see that parental controls are a popular request. I would like to add to other requests a time restriction. Not only hour per day but also time of day. Ex 1 hr per day and also 9pm through 7am. Children sneak and many children live in different homes with each parent. Not recommending for under 13 seemed like a "cop out." As it's not like 13 and above are mature enough to not sneak.
