About DeskTube
A desktop application which allows you to view, search, comment, upload, and download videos from YouTube. While watching a video, you can view the current user’s profile, which allows you to see their friends, videos, and favorite videos. You can also download the current video in MOV format for your enjoyment later.

DeskTube features an auto-updater so you’ll never be behind the times. Its constantly changing to improve performance, stability, and feature enhancements. It’s a great application and I’ve only heard good things about it so far from users.
