Another tip of the day (TOTD) series for Logos/Verbum 10. They will be short and often drawn from forum posts. Feel free to ask questions and/or suggest forum posts you'd like to see included. Adding comments about the behavior on mobile and web apps would be appreciated by your fellow forumites. A search for "L/V 10+ Tip of the Day site:community.logos.com" on Google should bring the tips up as should this Reading List within the application.
This tip is inspired by the forum post: Bibles Missing in Text Comparison - Logos Forums
The Text Comparison tool is more flexible than many users realize, especially it their primary use of it is through the F7 key to view a passage in multiple translations. Some basics: the first Bible i.e. the leftmost, is used as the base text. All other translations are compared to it. If the requested text is not present in the first Bible, text comparison will produce an error message and not run.

The first option (identified by the red arrow) is "show differences". Black text matches the base text; blue text indicates that it differs from the base text; red circle means text omitted from the base text.

The second option is to show the base text in all the texts.

Both of these options can be accessed through the Panel Menu. The choice of a horizontal or vertical (or automatic choice between these) can only be made through the panel menu. Note that the panel menu also allows options to ignore case (upper/lower), marks, and punctuation in the comparison.

There is a final choice between verse or interlinear format. You will note that this ignores several translations. The reason?
It's because only a few Bible have been aligned for interlinear text comparison purposes. This actually requires more than just having a reverse interlinear.
If you need a specific translation that is not available, request it through Roadmap | Faithlife for example Update Text Comparison dataset to support the NABRE | Faithlife. Also note that the options discussed above apply only to the verse format; they are ignored by the interlinear format.

Also remember that Text Comparison works for any versified text not just Bible text.
