Say you need to do a manual pentest on a web application with a lot of client-side code, like a single page application of the AngularJS sort.
It would be very helpful to understand how the app transitions through different states based on DOM events. For example, which flows lead to which results, and also the steps for those flows.
What we're talking about here is basically a client-side crawl.
With a simple script, you can print-out the client-side crawl that SCNR does and keep those result at hand to help you with your manual audit.
