Works, very small, no complaints.
I want to like it, I really do: a simple editor for a simple data format. Unfortunately it just doesn't deliver. The color coding works. The formatting works (though the option to auto-format on save would be nice). The outline kinda sorta works: it has a tendency to collapse on refresh forcing you to re-expand a lot. The validation just does not work consistently and frankly that is the most valuable part. It manages to flag some errors sometimes (missing commas for example) but it isn't consistent and it doesn't catch some really glaring problems like the closing bracket being missing from a list or the last curly brace missing from the JSON body. Too bad. :(
