I see the advantage of not moving the trend until it reaches the right end and then it jumps back. I don't like that it jumps all the way back to the center of the trend. I'd like an option either to select smooth/continuous scrolling, or to let it jump back only one major division or something so that there isn't so much wasted empty trend space just after a jump. Maybe both if it isn't too hard. Is it already there, and I just haven't noticed the option?
