I don't believe this capability exists in Logos. I'll try to explain what I'd like to see, with a screenshot from Accordance below. I'm asking for this feature for two reasons: 1) Because I could really use it when in an instructional scenario (versus preaching); 2) Because Accordance and BibleWorks both have it, and from every indication I've seen of people using those programs, this is the main way Bibles are displayed / used in those programs (screencasts where its use was incidental to the purpose of the screencast, i.e. not an ad for the product; in-class or in-person study scenarios).
In case someone is already thinking "Text Comparison," I'll address why I think it's insufficient below.
Here's a screenshot from Accordance:

Note two things that I'd like to see in Logos:
1) Multiple Bible versions in a single tab / panel. It's three different languages here, but it should work for any Bible. There is minimal display clutter between the different versions. There's a single reference that controls where each version is, so they navigate together.
2) The mouse is hovering over a word, highlighting that word, and the other Bibles will also highlight that same word automatically. I'm guessing the Bible has to be morph-tagged for this to work, but that's really another ought-to-have feature.
I know Logos has Text Comparison, but I don't think it fully meets what I'm looking for. a) It's not great at large passages. This should work for general purpose Bible display, just like a single Bible panel does today. b) I can't click Bible reference links in some other tool (search, a commentary, etc.) and have Text Comparison be the panel in which the referenced verse is opened. I could set the Text Comparison link set to a panel with my primary Bible and get it to the right place by side effect when I click a link. But that's clunky, and Text Comparison only displays a single verse at that point. c) It doesn't meet requirement #2 above.
If someone can enlighten me on how to achieve this in Logos, I'd be grateful. If I need to explain further, let me know. Otherwise, I'd love to see Faithlife implement this in, say, 6.2. 
Thanks,
Donnie
