Currently if I select a bit of text in one bible (e.g. NASB) sympathetic highlighting also shadows the text in other bibles (e.g. ESV). [y]
If I then apply some "permanent" highlighting via CTRL-K or via the highlighing pane to the first bible (NASB), nothing at all happens to the ESV.
I would like to suggest that within Bibles, highlighting the text be tied to the underlying interlinear text rather than to the surface text. That way "sympathetic highlighting" would reflect the same highlighting schema's in all Bibles.
Truly a win!
