I just shipped a feature I've wanted for a long time: find a file in Canvas, send it to your iPad, annotate it, and drop it right back into your workflow.
Under the hood it's a secure file handoff with real-time sync, and it's fully user-controlled. Nothing happens unless you click. But the tech isn't the point. The point is going from finding to opening to annotating in seconds. That's the difference between a tool and a workflow.
