Hey all. I have a MBAir connected to a 27" Samsung external monitor via thunderbolt to HDMI adapter at my desk. My question is, when I leave my desk to attend a meeting, or otherwise, I disconnect my monitor and anything open on the external monitor "desktop 2" gets moved to "desktop 1." I am looking for a way to have the external maintain it's space, and just shift to the laptop monitor. Then when I return to my desk, plug in the external, and boom, space moves back! Is this possible? I haven't been able to figure out a way to make this happen yet. Thanks!
