Being able to clear notification cards one they’ve been read would help to keep the UI a bit cleaner. For example, the Yesterday’s Day in Review card pops up, which is great, but I can go to the day in question and see that day’s info in the Day in Review card for that day. I don’t ming the reminder this morning to review yesterday, but I’d love to be able to make it go away. Fewer but more meaningful notifications. Relevant nudges after poor sleep or spikes, with guidance on what to do next.
