In the upper right-hand of your Overview screen, you will see your alerts. Consider this to be your Applogie task list.  By clicking on the alert, you can view the details, go directly to the details page for that subscription and hide the alert.

After you click on an alert and visit details page, you may want to continue to view the rest of your alerts.  The alert icon will always be displayed at the top of the screen.  By clicking on it, you can continue to work your way through your alerts.
