I second this. This would be awesome.

I am dabbling with this now. I'm able to turn DND off/on globally, but I don't really want to do that. I just want to decide which notification make a sound, and which ones don't.

This is quite fascinating but also interesting.

For each of the 5 priorities, I create an Android NotificationChannel, for which I can set setBypassDnd flag. However, I can only set that if I have a certain permission, for which the user has to manually toggle a setting in the Android UI. That wouldn't be a problem, except that a NotificationChannel, once created, cannot be updated ...............

Rubber ducking apparently works, even when typing it out 🦆 🦆 🦆

Looks like channels can be updated and when the permission to edit DND has been granted, setting setBypassDnd after the fact on an existing channel works.

I think I can work with this 🥳

So I dabbled (binwiederhier/ntfy-android#25), but we decided via Discord that we'll not programmatically change the DND override for individual channels in the app. Instead, I'll just make a menu item to "Override DND, sound and vibration" which will open the Android "Notification Settings" dialog. I'll also write some docs.

Fixed with this^^, but I'll add some documentation too, so I'll leave it open until then.
