add the option for YouTube video playback in a dedicated app on the phone
YT video playback in a dedicated YT app on the phone. The German WParea app, for example, gives you the choice to have YT vids played in the MetroTube app if installed instead over the YT mobile page.
This feature was added in last update. Option to open YouTube or Vimeo app will show up in articles. http://bit.ly/1aVTsVa
