Smooth scrolling and smooth "back to top" by activate and forget.
This plugin makes your anchor text to smooth scroll adds a smooth scroll to top feature/link in the lower-right corner of long pages. Appears after a set scrolling point and hides after scrolling near the top. This plugin is based on cudazi's plugin "Scroll to Top", and you may use this plugin if you need "Scroll to top" feature.
BTW, The plugin should be now compatible with many plugins. Please report compatibility issues here or on the GitHub repository. You are more than welcome to contribute towards the development of the plugin. For any support ask here: http://www.wpavenue.com/help/.
However, I have checked the plugin is working fine on Firefox, Chrome, IE and Safari for Windows.
