A must-have

This is a fantastic app. It offers many great features that Googles YouTube player lacks, such as continuing to play audio when you jump out of the app, great picture-in-picture support, and 4K video.

I would love to see a version of Protube for the Apple TV (totally willing to purchase it as well).

Edit: Not the apps fault, but 4K no longer seems to be available. I am seeing 1440p max.
