- I just tried this out to see what my API response was returning, the visualization made my debugging 2x faster. Really nice to have this extension as I don't need to copy this someplace else to see a structured collapsable view to see the first level of keywords, this helped me reduce the crowding in the API responses. I feel a customizable card like structure would be cherry on the top, like we play with cards may be and get a sneak peak of the essential details only :D
