I was dreading the shift to 5.7 since much of what I've been doing in 5.6 is sort of on auto pilot. I needed an introduction to 5.7 that made sense. That's exactly what is provided. In under a half-hour I got a feel for the basics and I got over my resistance to 5.7. PLUS the theme itself is terrific and makes a great starting point. Thank you. This is SO helpful.
