First, I pass the JSON to the tool. Then I extract all the paths I'm interested in (for debugging, testing, or demoing to a co-worker). Next time, I just pass in new JSON data and instantly see those fields.
I'm too lazy to copy and paste, so the tool supports extracting JSON paths by clicking on the JSON key.
It's a nice-to-have tool - not essential - but it helps me reduce some clicks and makes working with JSON a bit smoother.

Any feedback is appreciated.
