It would be great if you could choose to either share for review in Illustrator artboard by artboard (as exists now) or to share the entire pasteboard/drawing area so a reviewer could see all of the artboards at once. View the file exactly as the author sees it, akin to how Figma does it. Sometimes the finished area is helpful for review. Other times, such as early in the design phase when you're really just ideating, sharing the whole mess makes more sense. I currently screenshot the whole thing, but that makes commenting harder.
