myTube is a YouTube app built to keep your video playing no matter what. By lightly fading the video into the background, you can continue to watch while you read comments, browse channels and videos, and everything else you can do in the app. If you can do something in the app, then you can do it while watching a video!
One of the best examples of a great Windows 10 UWP app.
P.S. I've actually been using this app since the days that it was a Windows Phone 8 app. The developer has been doing an amazing job for years!
