This extension was built out of personal frustration.
While there are other extensions that implement "Back to Top" functionality, none (that I've tried) allow the user to go back to where they scrolled up from.
So the point of this extension isn't that it takes you to the top, but also allows you to undo that action.
If that isn't useful to you then this extension will have little utility for you.
Let me know if there are other things I can do to improve this extension.
