Yes, I have to work hard to limit my non-writing tinkering, so I timebox the design stuff pretty harshly.

I started the book four years ago, so the first design was unreadable on mobile devices (fixed position navigation will do that!). After a number of complaints, and the creation of Google Web Fonts, a mobile-friendly better design was a necessity.

I just finished another redesign that will launch when the last chapter is done. It's even more mobile friendly and has a front page that reflects the completed status of the book. It also just looks a hell of a lot better. :)
