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. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
