Hints about what to do
Q. Can I zoom in and out on the drawing, or pan around? A. No, maybe someday. Right now you are limited to the size of your browser window.
Q. Can I add multiple layers, sheets, or pages? A. No. Best you could do currently is open multiple browser tabs and save the projects separately.
