### Questions

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.
