In Safari in 10.5, I created a "web clip" for the YouTube "videos being watched right now" area -- just press the Web Clip toolbar button, move the highlight area over this section of the screen, and press Add.What's really neat about this particular web clip is that if I you click on a video in the Dashboard widget, it plays directly in the web clip itself! Basically, you can view a YouTube video without leaving the Dashboard. Normally, these links open in a regular Safari window (or your default browser). I created a short YouTube demonstration of this feature in action.
