There's two types of additional tagging I'd like to eventually see happen in Logos resources down the road (although it would involve a massive undertaking by the Information Architect Team).
1. There's a lot of loose and random articles in commentaries, harmonies, etc. They almost function as a collection of "journal articles" scattered across our libraries. It would be nice if Logos could identify each of these self-contained, standalone "articles" and tag them so they could be searched for content easily, similar to the way we search journal articles today.
2. Many of the Bibliographies in resources are linked to other books in our Logos library, but not all of them are. It'd be great if slowly and eventually the rest were, giving us the ability to pretty much click on any Bibliography in any book and go to the resource in Logos. A lot of it has been done, but it'd be great to see more.
Thanks!
