YouTube has updated its Google+ app so that groups of friends can create video playlists together while hanging out on the social network. The app now lets anyone in a Hangout add videos to a playlist, as well as remove them or change the order that they're set to play in. And once you have a playlist you and your friends are happy with, you can save it for future YouTube parties or share it with any of your Google+ circles. The app is available in 60 different languages and should be a good way to share the latest viral videos with all of your Google+ buddies — just don't forget to wear your mask.
