I like the word tree in passage analysis. However, it would be even more useful if it showed verse numbers. If I'm looking at Dt 15, for 'poor' for example, I have to display a search pane below it, set to search Dt 15 for 'poor' (using the same translation as in the word tree) in order to make the connection about where the branches of the word tree are pointing. I'd rather be able to find those connections directly in the word tree somehow, such as by right-click, hover, or ctrl-click to open the verse in the Bible.
