I was thinking that a cool feature would be to highlight the repeated words in a passage. Words that are repeated in a passage are usually significant. In john 15 the word abide is used many times. The greek word meno is used even more times; sometimes it is translated remain or continue. Obviously some kind of filter would need to be used to remove conjuctions and the defenite article. Perhaps this could be made available for the passage guide and/or the exegetical guide. I know that this can be done manually through the visual filter.
