First of all, good job! this is a great plugin for social sharing!!!!
One question regarding to the 'email' share button -
I am aware there is a configuration to Customize mail texts. And this mail text will be displayed + the url of that page as email body.
Is there any ways i can configure, when user press the email button, the email subject is filled with the post title dynamically, and the email body is filled with the excerpt? Of course, it would be great if it capture the feature image as well.
