uTubeVideo Gallery has been finally updated to version 1.7.1 which corrects a problem with adding Youtube video playlists as well as a video sorting issue. I do have additional features planned, such as different gallery views and style options, but wanted to get this patch out in the meantime. One other feature of note is the ability to use youtu.be links now when adding videos.
In order to use the updated playlist feature for adding playlists from Youtube you must now have an API key. Check out the documentation for directions on how to get one. This change is due to Youtube doing away with the previous version of their API and now requiring everyone to have an API key.
