I've been going through the first 3 chapters and am constantly finding one problem that has been bothering me. I wish there was a small little drawing or figure showing which snippets of javascript go along with which pages of html/php. For example, displayFrame page -> displayCustomerInfo(). For me at least, seeing this visually helps correlate how the pages along with the javascript all relate to one another or tie together. It's not a big deal since I can write it down myself, but if you guys do decide to post up something like that, I know I'd appreciate it very very much! So far, this book is very informative and I'm really enjoying going through it. I'm struggling a little with the predictive fetch example at the beginning of chapter 3, but I'm sure it'll all make sense once I re-read it a few times.

I just downloaded the book examples from http://www.nczonline.net/downloads/ and that definitely helps clear things up much much better.

I'd recommend downloading the example code and looking through it as you read. I think that will help.
