If you have Windows 10 installed, you can turn on the Notifications Center and have it show up - but don't get too excited, as there is not much else you can do as it's not fully functional, yet.
New information about Windows Phone 8.1 is constantly being revealed through the leaked SDK, and now it's understood that the Action Center will be able to show up to 20 notifications from each app.
Windows Phone 8.1 will reportedly launch with two long-rumored features: a notification center and virtual assistant called "Cortana" that operates with natural language, similar to Google Now.
An image allegedly of Microsoft's Windows Phone 8.1 update shows the ability to select multiple tiles as well as another glimpse of the operating system's rumored notification center.
New and improved Notifications are now live on Google Chrome beta builds. These bring new features and come alongside a long-expected Notification Center that lets you adjust notification sources.
Unification is finally available in the Windows Store. The app gives users a cross-platform notification center for some of their apps. The app is also present in the Windows Phone Store.
