An updated version of DeskTube was just posted. New in this release:
*Bug fixes
*”Options” button when viewing a video – This took the place of the full screen button, and now houses the “Embed Link”, “Link to”, and “Comment”. All future video related features will be under this “Options” screen.

Grab yourself a new copy if yours doesn’t automatically update when you launch it. As always, you can find it HERE
