Yesterday’s update to OS X Lion Preview 3 adds a very helpful new “Do Not Disturb” feature for notifications. The feature is a toggle accessible at the top of Notification Center that allows users to block incoming alerts and banners. The feature is very important for those who look to focus entirely on the content they are currently working on and do not want to be bothered by new emails, iMessages, calendar alerts, or other types of alerts.
This feature makes a lot of sense in Mountain Lion, and it would not be a stretch to expect an iOS-variant with iOS 6. OS X Mountain Lion’s Notification Center is accessible with a swipe to left on a Multi-Touch trackpad or with a mouse button click on the top right of the OS X menu bar.
