How can I manage app notification quick and easy?

When you touch and hold a notification on status bar, there will be two options appear “Prioritised”/“Alerting” and “Silent”.
1) Select “Prioritised” / “Alerting” to allow sound alert for this app at subsequent new notifications.
2) Select “Silent” to mute all notifications from this app
You can go to “Settings”->”Apps”->select the app you want to set->”App notifications” to further setup.
