If you use an external drive to share music, photos or other files, then you should know about the "Ignore ownership on this volume" option. This allows you to have multiple users on the same Mac, or multiple users across several Macs to have the same access to files and folders regardless of which user put them there. It can greatly simplify sharing the data on an external drive.
With "My Queue" you can quickly save videos to watch later.
To add an item to your queue just click the sign next to the video.
Once you've added a video visit "My Queue" to start watching!
