Remove render blocking resources Hummingbird

Hi there, I have been using Hummingbird today to get this website up to speed (getting great results too!)

I have now reached a point where it looks like the actual hummingbird js & css is left on my list of elements slowing the site down / effecting the pagespeed.

This is what I am getting in my report:

BENCHMARKS

None of the above-the-fold content on your page could be rendered without waiting for the following resources to load. Try to defer or asynchronously load blocking resources, or inline the critical portions of those resources directly in the HTML.

Remove render-blocking JavaScript:

Optimize CSS Delivery of the following:

Is there a way to improve this?
