Skype has updated it's application for Xbox One to do the opposite of what it was doing previously. Skype made a "Snap" upgrade for it's application for Xbox One. Old Skype application allowed you to Snap other apps into Skype, this upgrade allows you to Snap a Skype video call or voice call into other applications.
"With this update, you now have the option of keeping your games or movies as the stars of the screen. Once you are in a voice or video call, you can control the call within Snap, whether you want to add another friend to the call, turn the camera off or hang up, all without leaving your other activity."
Now you call add more participants to your call and enjoy watching a movie with your friends, TV show or live sports together, See your best friend’s face as you narrowly beat them in Forza Motorsport 5 or watch your mom’s favorite movie while on a video call with her as Skype noted at their official blog.
It's not a very big update but in my opinion it's very good, do you agree?!!
