The Animator

@Dan whenever i press save it undoes whatever i did last so i have to keep fixing it

also when i press undo it goes back 5 - 6 lines instead of the 1 i want to fix its really annoying

The second one might be caused by dragging the line off the canvas and then drawing another line, dragging it off the canvas. So when you undo, it undoes all those off canvas lines.
