Thank you! This is great!
Autoprefixer is with no doubt the thing that I miss the most as currently my system-js-working-pattern-library looks like a motorcycle incident at high speed. However I see the “plugin” part in the git file, and I think I should be able to install also the others plugin for PostCSS that I use in that section.
If not, too bad! Autoprefixer is what I’m truly missing, unless I want to rewrite my whole PL with a lorry of mixins like I had to do before PostCSS.
