Very good functionality but problems with font types

This plugin is really good when it comes to the simplicity and usage, however it has problems embedding some fonts from google correctly.

For some fonts such as Open Sans and Roboto, the font face for the ‘bold’ types are missing, which results in the browser rendering the font via a ‘bolding’ algorithm when using font-weight:bold for these fonts.
This results in very bad text quality (blurred text) and could be fixed easily by adding all the google fonts with all their correct types.

Sadly, this currently prevents me from using this plugin.
