That's not what I mean, should have phrased it better. I don't mean reminders for events, but for tasks. "Do the bins today" and then an option to mark it as done. I know I can technically do the same thing with events, but I'd like a more convenient way of doing it.
It's a common use case but probably a bit out of scope for the team at the moment. It's probably better to have a seperate "todo" type of app for that.
When I enter something in my calendar from the phone app, there are 2 reminder set by default: a notification and a mail 15 minutes before the event start, and you can add more notification setting time and how (notification on the phone or email).
Same from the web, but to see/change them you need to go to the "More options..." dialog.
