The planned feature we have will be generally superior in every way, as it will examine the full text of the current outline chunk you’re working with and then scan for sentence-or-greater duplications of that text throughout the entire project, and generate a list of all documents containing those ranges of text, sorted by incident weight and highlighting them for you in both documents. It was a feature added a couple of years after v3 was launched though, so it was put on the post-launch list.
