Multi-Version Note Referencing
Make notes available for all versions of the Bible I own. When I take a note in my NIV Bible, I would love to see it in while reading the ESV or NASB or whatever version I'm reading through. That way I can see when I've taken the time to write down my thoughts regardless of the translation I'm in. It is still nice to know which version I took the note in, but it would be nice to see a hyperlink available in all the translations or at least my top 5.
If you take a note on a reference (as opposed to a specific word), it will be available in all versions.
Logos 7 includes the ability to see highlights (on individual words) across all Bibles (with reverse interlinears) by using the Corresponding Notes and Highlights feature: https://community.logos.com/forums/t/120644.aspx
