Absolutely love standby. It feels like one of those features it should have always had! I also love that it can function as a kind of bed time do not disturb mode. I’ve only tried it in an alarm clock context so far but it’s great for that!
The automated groceries list in reminders is also a game changer for me.
Under list info, you can change the list type to “groceries” and it will try to organize your list under grocery store section headings.
