Creating Flow with OmniFocus, Third Edition
This week Kourosh Dini released the third edition of his Creating Flow with OmniFocus book. This is, by far, my favorite book on using OmniFocus.
Kourosh has been using OmniFocus for years and has some great ideas on how to the most out of the application. The book covers concepts ranging from beginning to advanced and all of them are explained with Kourosh's gentle and insightful writing style.
