Brando9300 on YouTube gave us a suggestion to check out MP3Cut.net and it's pretty nifty! Edit, add fades, and more to your local audio files or even YouTube videos! Then save them back to your computer or as ringtones.
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!
