Oh, that is very helpful Cat. I will try to set it up so I can use the "next action" filter.
I found this post online which suggests that David Allen also recognizes that Omnifocus is not the best match for GTD:

eproductivity, which seems like the closest match for GTD and the system Allen himself uses, seems that it would theoretically be best--he says you can really dive deep into eproductivity using GTD. But eproductivity seems completely alien to the Mac and I am already committed to Omnifocus and have invested a lot of time in it. I want to make Omnifocus work really well for GTD and appreciate any help or tips.
