Hide desktop notifications until you're ready to look at them
Description
Do Not Disturb Button provides a panel button to temporarily hide incoming
notifications in GNOME Shell. A count of notifications appears next to the panel
button, and notifications remain hidden in the notifications message tray, until
you choose to show and dismiss them. You can also assign a keyboard shortcut to
toggle the Do Not Disturb status.
(Do Not Disturb Button allows you to set the "available" or "busy" status for
desktop notifications only, not the status of chat or other applications
connected to GNOME's Online Accounts.)
