It would be great if you could navigate immediately to a particular verse in a particular version that wasn't your default version, by typing the verse reference followed in parentheses by the version abbreviation.
I tried it just now, on the hunch that maybe you guys might have thought of that for Logos 4, but no such luck. An attempt to navigate to Rom 6:1 (ESV) directly brought up the Search window with a search of my entire library for that text. And the stuff that was found was completely irrelevant!
