UniTube v1.6.6. rebrands the app experience as UniTube. The app includes full-size, resolution-qualified UniTube tile icons. Signed for Developer Mode sideloading with the included ZuneTracks development certificate. Install UniTubeReleaseDevelopment.cer before deploying the ARM AppX. Also an x64 appx is provided for those that want to try the experience on Desktops.
UniTube has an embedded API key for YouTube browsing via "Trending Now" section, "Search" pivot, and "Categories" pivot. You can also sign in to your YouTube profile by tapping on the Settings button, scroll down to the bottom and tap "start google sign in". You will need to go to google.com/device and enter the code that appears at the bottom of the app, attach the app to your YouTube account, and proceed through the warnings (UniTube is currently in approval process and the warning page will go away). Once you complete the sign in process, your Profile should now be viewable within UniTube, and the Video uploader will allow you to upload any video to your YouTube account. Currently all videos are uploaded as private and this can not be changed within the app.
