Review for JS Deminifier by swigger
Rated 3 out of 5 stars
I suggest you add an option to de-minifier js on download, just as the older version of js deminifier did. That makes downloading a bit slower, but gives a banifit that deminifiered js code can be seen in firebug source tab, so someone can add breakpoints on some lines.
