Prefer asynchronous resources

Hello! I use your plugin! So far I am satisfied! However, when I test my page on Gtmetrix it shows me this at the results:

Prefer asynchronous resources
mysite loads https://connect.facebook.net/en_US/all.js synchronously.
mysite loads https://platform.twitter.com/widgets.js synchronously.
mysite loads https://apis.google.com/js/plusone.js synchronously.

Is something that I or you can do to load those js files async?

Thanks
