This plugin allows you to quickly scroll to the top of the page by clicking on the left empty area of your website. Second click will take you back to the original position.
It works smoothly with fluid and fixed forum width - clickable area will be automatically resized depending on the available space. Even if you use 98% fluid width it's still easy to throw the cursor to the left and you would never miss the clickable area.
The plugin is visible only on the desktop view (hidden on tablets and mobile).
