Love the book, really helping.

Two things on my book wishlist:

1. Mention the Chapter numbers on the tops of all book pages - just makes it easier to leaf through

2. Display the code line numbers in the excerpts in the book - again, just makes it easier to find stuff, saves a little time

I REALLY like how everything is displayed in the book, the "visuality" (I know, agonizing) - my point is that the pages and layout and colors are easy for the eye to follow, very helpful for learning, thanks
