Today at Build it was revealed that Notification Mirroring and Universal Dismiss are coming to Windows 10, Mobile, and Android devices. The service is an upgrade to the Windows Notification Service (WNS) and, for now, will work through Cortana, but later will go through the OS. The news was revealed in a session entitled 'Notification Futures: Action Center in the Cloud and the Windows Notification Platform' and details about how the Notification Center is moving to a Cortana-MSA mediated system.

The new app feature will let developers add the ability to dismiss a notification across all devices universally. For instance, you could be on a PC and receive a news alert. Using 'universal dismiss' will remove that app notification from your phone and vice versa.
