Restore Scrollbar Position for Mac

How many times have you scrolled the webpage a certain distance and suddenly want to "peek" at sometime at the top or bottom of the webpage without losing your current scroll position?

If I scroll back to the top (or bottom) of the page to review part of the webpage, there is no guaranteed way to return to where I was.

On Windows systems, this is easy because when dragging the scrollbar using the mouse, if you keep the mouse button held down, and move the pointer sideways for about 100 pixels, the scrollbar goes back to its location before being dragged, and the webpage with it.

Mac systems have not implemented this super useful behavior, but with this extension you can now have a similar feature too.

To quickly scroll to another part of the webpage and easily jump back to the current position, simply drag the scrollbar to the desired part of the webpage, and without releasing he mouse button, drag the pointer away from the scrollbar at least 100 pixels away and then release the mouse button.
