How can I add notes to a Bible passage that are viewable across all translations with that passage? Is that possible without adding a separate Document?
Yes. You must add the note to the REFERENCE, not the SELECTION. Is your question about mobile or desktop?
I use both mobile (iOs) and desktop (Mac), so I'd like to know how to do it in both versions.
I am not in a position to post screenshots right now. I'll walk you through it, but if you need more help let us know!
