Add "Early Church Fathers Overview" back into Logos 5.
The Logos 3 ECF collection included a resource called "Early Church Fathers Overview," which was a TOC of all 37 volumes. This is not included in the Logos 5 edition of ECF. (it is in the Catholic edition, but not the Protestant edition). If you were looking for the writings of let's say "Polycarp", you didn't need to know which ECF volume to open, but you could search the Overview. I know you create an ECF collection and search for "Polycarp" in the collection, but some of these authors are referenced by many other early church fathers, and it is difficult to weed through the results to find what Polycarp actually authored (especially since he may not have referred to his own name). If you can search an Overview, then his writing will stand out easily. And the Overview had the links to open the resources.
