For my APIs I have some very large JSON structures and I love that I can search through the structure in the bottom half of the panel. When making changes though I still have to scroll through the entire snippet looking for the spot I want to adjust.
The experience would be even better if I could make the search in the bottom half, double click the row I want to go to and have it jump to that area in the top snippet portion. It would make adjustments to the JSON go much quicker when I'm working with a large structure.
