I'm not sure if docking to the right is really the best default; it really depends on your setup. On big, wide displays it's indeed a good way to do it. On small displays (notebooks) docking on the bottom is better. If you have multiple displays, detaching and moving the detached window to the other display works best. I think it's a good idea to assume the worst (tiny display) and dock to the bottom; the browser will remember your setting anyway so it's not like you'll need to do this all the time.
