So we can resize the canvas during art. Ex; Red is leader, they want to expand the canvas so all 41 friends have a section.

cropping the canvas would be really useful, expecially since im really bad at gauging how large of a canvas i need and usually end up creating a canvas thats too large for my works or have the wrong aspect ratio. usually if i need to crop it i have to export it then crop it in my files then import it back to the artspace, and its really inconvenient

You cannot change the canvas size one you have created something, so if i want to add more space, etc. it is not possible (unless you make a new one and copy your artwork onto it, which is annoying).
