Easy Social Share Buttons is the most complete social media plugin for WordPress. You can easily turn on or off functions or modules based on your needs. This modular structure makes it easy to fit the plugin for every website or every need. And also helps to optimize its usage by deactivating the code and assets from the modules you are not using.
You can access the features screen from the top-level menu item activate/deactivate features (the numbers shows active vs all available features).
