You can post the table link and people can edit it easily with their shot idea and repost it. And everybody is using the exact same layout. Plus there are diamonds on the table so you can line things up more exactly. You have the balls the actual color and it's a realistic looking table. I think Bob Jewett has said the ball size is not perfectly relative to the table size, but I think it's going to be better than a semicircle on a napkin. You can draw the actual paths of the cueball with a solid line, and the path of the object ball with a dotted line, for example. There's no need to label the rails as you can quickly draw out the exact shot. If that fails, the orientation is always the same so top/bottom and right/left will work.
