How to make it FULL responsive?

The plugin is good! but I have question, the button is responsive, but not fully responsive. Like when it is on the smallest screen, the button still appear Icon + text, not the icon only (so that the G+ button been cut most of it).

You can see it here: http://houseofinfographics.com/karakter-dragon-ball/

And one more, why is the twitter sharing permalink is not the same format as whole site? I set permalink to use custom url, but when being tweet it use post ID as permalink.

Because it will be a problem for my twitter share count.

Thank you in advance.
