It also makes it much, MUCH easier because, lets say you are drawing a shape like a face. If you can sketch an outline and then make one side just like the other, it would be easier. And then you would be able to see the live effects taking place without having to clone, like adjusting a center point so you can see it will be right without having to keep cloning and flipping. Plus, if you just draw an outline of half an object, there would be a line overlapping a little or going through the whole picture, depending on how you set the outline. Having live-effects of all objects would be a great and unique addition to make lots of free-hand art easier, and cloning and flipping is really just a work-around to what this feature should be.
