For some reasons the Google fonts API is not available in China mainland, which seriously slows down the website.
Currently I commented out this line and then add some font style in custom css section for a workaround.
I know this is not suitable to request a feature for something so specific, however this could be extend to a generic feature, to easily integrate with many CDN providers and speed up the website.
And, a option to set static files URL prefix. This prefix could be a CDN address, like MaxCDN, CloudFront or KeyCDN service URL, so that all static files including scripts, styles, avatar images, will be loaded directly from CDN cache. This could reduce requests to host machine, and significantly decrease loading time.
Of course, those features can be implemented via extensions as well 😃
