Another idea to go with this is automatically gear it up to increase the scroll rate by whether you are continuously holding down. So after 2 seconds jump to 10 at a time, and after 2 more seconds jump to 100 at at time.
Oh my, the add a search bar request is two years old already? There is room for major improvements to the interface. I was wanting to go back and improve levels I performed relative to other players, but there doesn't appear to be a way to search for how many you are showing 1st, 2nd, etc.
