Picture this: You are deep in a debugging session. Your primary monitor is consumed by your IDE, your secondary display is packed with terminal sessions tailing production logs, and you suddenly need a dedicated, isolated window for a mobile web inspector, a database GUI, or a real-time system monitor. You reach for your iPad or iPhone sitting idle on your desk.
