To get a sense of how in-depth an author discusses a passage it would be useful to sort commentaries by length or word count. This would ideally work from the commentary guide which can already be sorted by various categories.
Currently the only work around would be to go through each book individually via the concordance tool and restrict it to the passage at hand.
