This is a quick fix, but it will be a huge esthetic improvement.
The move should accelerate for a while, then move steadily for a while, then decelerate to the endpoint.
Two good ways of doing it are to accelerate for half the time, then decelerate for half the time.
Another way that I think looks a bit more natural (as if a human hand were involved) is accelerate for 2/3, then decelerate for 1/3.

It would be useful to be able to set/get the duration of the animation.
