This tool allows to edit css file in line of HTML file. So basically if you’re looking into you body tag, you tool will find all related css parts for you to edit in-line. Just few weeks ago it would save us (Me and Tor) at least few hours of work when we were editing JQuery CSS files.
There are no final version yet (developers claims that they are using this same tool to develop the tool itself for quite some time already, so it should be quite good), but it’s available on git https://github.com/adobe/brackets
Didn’t have time to try it out now, but definitely will and provide a feedback here.
edit:
With help of Gareth forced it to run:
