A great tool
It does what it says it does. It makes editing Json easy, and one can see (and cut and paste) the Json below each level. A stand-out feature is that you get a full text box for strings, and you edit the string un-escaped (with newlines, etc) and its stored fully escaped. Ive rarely seen this in XML editors. It lets you move nodes around (even key/value pairs, even though this doesnt really make a difference, but makes the Json more readable) and make a nodes into an object or an array. One can even edit true/false values from the view screen.
My only issues (and they are minor) is that it lets you add keys which already exist in the object, and when you create a string node, it starts out with "string" as the text (I would have preferred blank).
