This is a tiny but useful plugin to add a simple icon in website bottom area. When you will scroll down a while, this clickable icon will be visible and after click it will take you to the top of the page. You will have a settings page under Dashboard-> Settings -> WPFY Scroller. There you can customise your icon design.
