Social Media Floating Plugin configuration flexibility

I found the social media floating plugin implemented here

1. Can I configure this plug in so that it just does the twitter and forward email option?

2. I would like to add an easy frictionless post to facebook while posting a comment to the blog capability.

This is starting to look like it might require a link to a stand alone page to accomplish. If it does can I add such an icon and a link to the menu provided by the floating social plugin?
