In addition to the improvements to the Universal Windows App model, Microsoft is bringing new improvements to Action Center in Windows 10. To improve the look of notifications in the Action Center, Microsoft is now allowing apps to have hero image, app logo and more complex layouts. Check out the image above. Also, the notification listener will allow your app have sync between notifications and tiles.
Microsoft is also promising better notifications performance, thanks to the upgraded infrastructure on which Microsoft is ruing this service. The most awaited Notification Mirroring is also coming. If you dismiss a Twitter app notification on your phone, it will be automatically dismissed on your PC as well.
