I think motion blur could enhance UI animations by making fast transitions feel smoother, even with the low number of frames the animation has to be rendered with. I wonder if this idea has been explored in mainstream UI frameworks, and if not, why - is it too computationally expensive, technically infeasible, or just a bad idea.
