It's so damn good... Rated 5 out of 5 stars

A little gem!
It still needs some polishing, like ability to clone and move up/down for profiles/switches/states. Plus moving settings from extension dir to profile would be a good idea... despite that it's one of those extensions that (in skillful hands) can replace many, many others! Simple idea behind it that makes it so damn good ;)
