Hi, nice Addon. For me, the possibility to slow down with Alt+Shift+Down doesn´t work. When I Alt+Shift+Up I cannot cancel it to bring it down . And could you rewrite it, that I have the choice, that when I´m at the end of the page, the function does NOT deactivate (bc some websites load slow, your script recognizes it has reached the end of the site and deactivates). This would be really nice! ♥
