Adds a button and keyboard shortcuts (down and up arrows) that scroll to quickly and smoothly navigate to the next/previous top-level comment. This scroller saves time by allowing you to skip comment threads you're not interested in. An alternative to collapsing the thread.
Great script but I wish you added another button to go to the previous top level comment. The keyboard shortcut to do so is there so I don't see why not. Right on top of the next comment button, so theyre both located near each other.
