Well Autofocus is indeed powerfull. I have worked in parallele with omnifocus and AF and the winner is... Autofocus. Very worry about that because i indeed like OF but the fact is that except for project management in context it's less efficient. So i only use OF for project management. I tried to modify context creatings pages (see on my blog : http://gtdway.blogspot.com) but at the end of the day it was really impossible to handle with OF. Instead AF worked perfectly well and i had a very good vision of all my tasks and aims. I am waiting for the last version of OF 1.7 ? hoping they will do something more powerfull and easy to handle. Fo the moment i agree with "AF is the killer of any app for working days tasks and i am sad to might saying this.
