Rule-based notification toggle

Don’t have a good place to log this, so I’ll put it here and see if it draws comments.
I used rules for the first time yesterday. I tired ‘mut notifications’. It worked. Too well. Even after I tried to ‘unmute’ by writing and executing a new rule I could not get notifications to turn back on. I had to stop the app, clear the data, uninstall the app, and reinstall it to get notifications back on.
