Alright, so if I have a place to draw lines on a form, with a pen and a graphics. How can I keep track of them, so I can update their individual positions if I need to.

There will be a drawing canvas, as well as a list of the drawn lines, and their points, where you can edit the locations and the lines will update.

Would an array do it? Or what? Can I even change the individual Xs and Ys of the lines?
