Despite the strong emphasis on style, the plugin is incredibly lightweight. Social Media Feather uses no Javascript at all, which means its super-quick to load! There are a number of premium Country Email List extensions available, including extra icon sets, and a cool-looking greyscale effect.
Social Share & Locker Pro is a fantastic two-in-one premium plugin, available for $14 from CodeCanyon. For your money, you get both great-looking social sharing buttons, plus social locker functionality.
The most important 20 social media channels are supported by the plugin, and your share buttons can be placed anywhere on your page — top, bottom, left, or right. They can be fixed in an absolute position, or floated so that they appear on screen at all times. You can also place the share buttons directly into your content using a simple shortcode.
