Excellent add-on. I use it at work everyday and I'm more than happy with it. The highlighting feature has some limitations, though. The highlighting is based on the KelpJSONView.js which is using JSON.parse() and if you have some large numbers (longer than 15 digits) you lose precision and you end up with wrong values. That is happening because in JavaScript those numbers are saved as floating point numbers. A fix for that is to detect those numbers before calling the JSON.parse() method and convert them to strings for example.
