It looks interesting, but the screencast needs to be a bit more concise, and aimed at people who would actually use this. I made it through the first 5 minutes and gave up, because I wanted to see what the library did. I didn't want a tutorial seemingly aimed at absolute beginners, who in my mind wouldn't give two hoots about improved debugging at that stage.

Had there been a shorter overview of the cool things you could do, I might have got a better impression.
