The settings for Goodnight mode seem to keep changing. At one point in time you could set it so that it would learn your regular bed time and automatically prompt you that it would turn on that a certain time. I can't find that setting anymore and not sure why they would remove it. It was a nice feature so that you didn't have to remember to switch the mode each night.
