I have found on netbeans, sass causes it to crash losing the sass code you are working on. Also you cant edit with chrome extension. Sass needs to work both directions to be usefull. Also you cannot revert refactoring if you rename classes.
The main reason I wanted to try sass was to break up css code into sections.But I think there are better solutions in netbeans.
I also do not like the idea of trying to make css into something else.
