Does Gnome3 have a method to filter desktop notifications based on notification content? If so, how?
Desktop notifications are useful, and I know that it's possible to turn them off per-application.
What I'd like to be able to do is filter notifications based on the notification text (or other notification metadata, something like this rsyslog question). I have one application which generally sends useful notifications, and also (in a particular environment) sends a notification each couple of minutes which I'd rather not see.
The notification is a harmless warning but annoying, so filtering the notification would be a reasonable solution if the desktop environment supports this.
