Rated 4 out of 5 stars

Doesn't detect all valid json files but otherwise just works as expected. Will be a real eye-strain saver.

This review is for a previous version of the add-on (0.1b2). 

Example files?

a_kurogane, I'd love it if you would send me links to JSON documents that it doesn't detect (please file them in the issue tracker for the project on Google Code) - I'd like to make sure all valid JSON documents get formatted!
