The cover states that all features of the application are covered, and I can't claim to have discovered a gap. Each author (Kvern and Blatner) offers a deep perspective, and when they differ with one another, they say so. Thus the user gets two keen insights rather than the monolithic pronouncements so common in software books. This empowers the reader: a goal I try to achieve in my software classes. As I try to give my students enough information and methodology to make their own workflow decisions, this book does likewise. That is why I recommend this volume in my classes.
Be warned, however, that this is not a "how-to", or book of exercises. It is a reference. It is a perfect complement to my classes, but not a workbook for use during them. This gives the book usefulness well beyond the learning curve and into daily and even advanced use.
