Drawing lines, circles, etc
I would like to see the ability to create our own lines, arrows, and circles that we could have move across the screen in any direction we choose. For instance after you complete a problem you can circle it freehand. Or if you want to refer to something you could direct the viewer by drawing an arrow from one element to the another. Right now I don't see any line elements that you can resize, shape, or circle other than simply resizing it. Thanks.
