Is Proxy Supported?

[pillsilly]

How can I help you?
As title, I'm working behind a proxy and my working-well proxy doesn't seem to be taken by gramma, so doe it mean that it's not supported yet?

Environment: Linux Mint
Proxy Variables: http_proxy, https_proxy.

By the way the SW does looks awsome and with great potential right there. Thanks for your brilliant work ! @caderek
