- It was great overall, but when you want to view the records in collapsed mode, it doesnβt show the number of fields or the number of records in the list. It would be really nice to have that feature as well β similar to [http://www.jsoneditoronline.org/](http://www.jsoneditoronline.org/).

- Very nice! Just wish that empty arrays and objects were rendered as "[]" or "{}", instead of "[" (blank line) "]", 3 lines in total. I didn't find an option for that.
