@hhsnopek Hi, thanks for the reply. No, there is no scss/sass autoprefixer. The only one I know is the one based on PostCSS or integrated autoprefixer for example in Atom editor. By default Sass does not come with that as Stylus for example. I really love roots. The only thing I find kind of lacking compared for example to Harpjs (even though Roots are definitely more mature) is the documentation.
