It's happens that people close their notifications by a mistake (or is it only me?). So it's easy to forget about Anki's daily review if there is no reminder left.

Describe the solution you'd like
It would be nice to have an option (a checkbox in settings) to make a reminder permanent as a notification until a daily review is done. Then it just should destroy itself. Also it will be comfortable if this notification's counter of cards to review updates with new reviews done. So it would be possible to know how many cards are left just by looking at the notification after an interruption of reviews for any reason.

Additional context
I think there is no need in an additional UI update for the notification but a dynamic cards to review counter.
