Comment 34 for bug 428509

The problem that's blocked me until now, in designing a solution for this, is that a Do Not Disturb mode would so often be forgotten. To be effective, you'd need to remember to turn it on every time you launched the particular app, or went into the particular app mode, and turn it off afterwards. And often you'd forget at least one of those.

But System Settings on the phone already includes a design (not yet implemented) for controlling which apps can use notification bubbles at all. As the designs for form factors converge, I guess it makes sense for the PC to have equivalent settings. Those can then tie in to Do Not Disturb mode. You could let each app use notification bubbles at any time, never, or only at times when DND mode is off.

A remaining issue will be how to categorize notification bubbles that don't come from a particular app: for example, print jobs and Wi-Fi connections.
