I in particular liked to use it with Tasks.org client for non-dismissable reminders, so that they stayed in the notifications bar until I mark them done. This way I would never accidentally dismiss a reminder for a chore until I specifically completed it.
This right here. Exact same use case.
What I’ve started doing is setting them to re-trigger at random if they’ve been swiped away. At least then if I accidentally dismiss it, it’ll come back in a little while.
