RefTagger can parse Scripture references when the space is missing between the book name and the chapter, for example, notice how you can hover over the first of these three references and the right text comes up:
Micah6:8 John 3:16 Revelation 3:20
But Logos can't do it. Copy and paste that into a Note, or go to a Passage List and do Add passages from clipboard, and it can't figure out that the first one is supposed to be a Scripture reference.
