Ideally there would be a configurable escalation-to-the-same-user policy. I might want: vibrate-only notification, then normal notification, then critical notification, then phone call, in that order, with configurable delays. Ideally this would interact well with focus/sleep mode, so I could get a calm critical notification before full klaxons.
Other feature request: a way to tell the app to shut up already. I’ve occasionally dealt with an issue causing notifications every minute or so. The last thing I need while fixing it is more notifications to ack or silence.
