I have been asking Apple to add custom Do Not Disturb schedules (e.g. one for weekday, one for weekend) for ages. I lost count how many feedback requests and emails to Tim/Craig I've sent over the years. This seems like a simple addition to DND or Bedtime mode sort of like how they added custom schedules for Screen Time. I was hoping this supposed big change to Bedtime Mode or some kind of system-wide sleep mode would be mentioned at the keynote but nada.
Sigh.
Sigh.
