Great idea, but I'd lose the background audio. I can't stand background audio in tutorials but that's just me. I would suggest instead explanation as you navigate the different controls.
Outside of that. I would live to see tutorials for different front page configurations. Different ideas that would be considered more advanced block placements and such.
Thanks, great idea Mick.
Thanks. To be honest regarding the audio, well I do have really nice USB audio interface, but I don't have a decent vocal mic to use with it. I use it only for directly recording electric guitar.
Also the free screencast software I use doesn't have any way of adding text, so I'm kind of limited until I can get my hands on some decent software. Hence the music track.

I'll work on it though, and perhaps come up with a solution.
