Software options proliferate extremely easily - too easily, in fact - because too many options create tools that can't ever be used intuitively. Intuitive actions confine the detail work to a dedicated part of the brain, leaving the rest of one's mind free to respond with attention and sensitivity to the changing texture of the moment.
