Kourosh Dini (@Kourosh), who featured in MPU 78, 263 and Free Agents 40 has released an updated version of his OmniFocus book: Creating Flow with Omnifocus 3.

The @MacSparky OmniFocus Field guide refers to this (upcoming) book in the additional resources section.
I have the preceding version (v2) of the book, which I consider to be very extensive and with implementable examples. I will be buying the new version!
Agreed. Kourosh really does a great job on that book. I’ll be posting on it at MacSparky shortly.
