Same thing here
I'm in the same boat as Larry.
I've only CS3 and didn't even look at the requirements. It also works for me with the exception of the preview.
I agree, don't restrict it, maybe just make the notification more obvious/apparent for we who haven't or can't upgrade our Dreamweaver for economic hardships reasons like myself.
I used the Ledge as in the video as I knew what it looked like and works well on site.
It would be nice if perhaps a pdf could be made that had a screenshot of each of the presets so we unfortunates know what we're working off of.
Anyway, I also think it's really nice and am going to keep it.
