So far so good but...

A nice visual JSON editor that allows for quick brainstroming of JSON structures.

I do have a few suggestions
* Syntax highlighting in the Raw JSON window
* It would also be nice to be able to change the bracing style. Its understandable that most Javascript bracing styles are K&R due to the lovely behavior of Javascripts return keyword but in some coding standards, bracing style is required to be left justified.
* Change the behavior of the Key field so you dont have to press enter in order for the changes to stick. I personally do a lot of tabbing between fields and this burns me from time to time.
* Drag and drop reordering of the fields.
