In search results returning notes containing verse references, some three character book abbreviations are not recognized to be converted to links. Example: Gen, Heb, Hos, Exo, Jon are recognized, but not (in 4.8.7) Deu, Mar, Luk, Act, 1Jo, 2Jo. But Deut, Mark, Luke, Acts, 1Joh, 2Joh are recognized.

Allowing more book abbreviations would be nice but not all that necessary. See for example http://www.logos.com/support/lbs/booknames
but just consider some reasonable subset.

We may be expanding the set of book names and abbreviations that are recognized in a future version, but at this point, I believe the guideline is to use the full book name or the abbreviation as it appears at the top of the screen (or on the book chooser grid.)

I believe in 4.8.8 we expanded things to include the books in the standard Apocrypha set.
