Scrollbar Lens oleh emvaized

Scrollbar Lens shows a preview of the page when you hover the browser scrollbar on the right side of the screen. It helps to easily see the page as a whole, and quickly jump to any part of it by a simple click. Minimap will be shown only if page height is 2.5 times more than the screen height.
