Came across this old school post: http://blog.logos.com/archives/2006/08/genre_source_visual_filtering.html .
I would like to know how this could work with AFAT (great name!) in L4. I am particualy interested in JEPD (aka documentary hypothesis (DH) aka Wellhausen hypothesis), so a filter like the Eissfeldt Source visual filter would be gold dust, however the Andersen-Forbes Genre Tags visual filter looks amazing also. But I cant seem to find them in L4... thanks all!
