All admins with Google Apps experience will probably remember the Alerts and Notifications box in the Admin Control Panel. While this was a great source for keeping up with a domain, we think the new Notifications Inbox is a definite improvement.

The Notifications Inbox is very intuitive, to the point that it resembles the Google+ notifications box.

We suggest checking the Inbox periodically to keep up with feature updates and purchasing instructions for various products in the Google Apps suite.
