Or press the LEFT or RIGHT ARROW key on the keyboard simultaneously with the mouse-click, to generate draw/fade? Just an idea, saw this implemented in a tennis PC game, you could vary your shots & surprise your opponent with the direction of your shot in this way, even though the aim by itself was "dead center" or "straight ahead" by default, as it is in WGT.
UP and DOWN ARROW keys might also be used in this way to generate top spin & back spin, so we don't need to adjust this manually by dragging the dot on the golf ball. WGT has already implemented a great keyboard shortcut, SPACEBAR = ZOOM, why not more of them?
