This is a buggy plugin. I had issues with it on the first day I started using it. As a web developer myself I see some problems with it right away.
First of all you need to scope your css with unique ID just only to your plugin, so it would not affect website's styles or website's styles would not affect your plugin. After installing have some icons broken in buttons, just because plugin uses .fa-icon classes to style not #mySuppaDuppaPlugin .fa-icon.
Second to keep settings of a plugin in shortcode parameters is stupid idea. What if I have 100 pages using plugin and I decided to change social network button? I need to go all over 100 pages and paste new shortcode's parameter. Or use SQL find and replace, which I sure most of users will not do.
And today it just stopped reloading page after G+ sharing so users can't get access to files, and FB not working either. Waste of time and money. And I get 0 plugin updates in more than 6 month, even after release of WP 5.0
