 * Hi –
 * It is mentioned that the plugin has support for Critical Path CSS with CSS Async
   via LoadCSS. But I am unable to find that setting. Can you please help ?
 * Thanks a lot in advance !
    Regards.

 * Hi,
 * We added this feature a few versions back, but it has been since then removed
   and it’s now under development for the future.
 * Basically, I removed the CSS async option, because async doesn’t preserve the
   order of the css files, and most people end up with more than 1 css file generated.
 * Async would make sense, only if you have a single, merged CSS optimized file 
   per page (plus the critical path css), else css that was originally defined later
   can end up loading earlier and be overwritten by another async css file (it’s
   random, you cannot predict which loads first).
 * I’m still looking into this for the future, but if you’re doing critical path
   optimization, you could “collect all css and then do uncss with gulp / grunt 
   instead of looking for the critical path”. That however, not so easy for a non
   developer.

 * Hi Raul –
 * Thanks for this clear answer.
    Good idea, I will try uncss. And thanks again 
   for this great plugin.
