Switch between spaces with just one monitor in a two monitor setup

Hi. Maybe this is already possible, but I couldn’t figure out how. Title kind of says it all. Use case is this: sometimes I attach my TV to my laptop. I’d like to open a video in chrome, put it on the second monitor, but not change my workflow for when I have just one monitor. So second monitor should stay fixed while allowing me to still move around in spaces with my first monitor (laptop).

That’s possible in TotalSpaces2 with Mavericks if you have “Displays have separate spaces” checked in Mission Control preferences. Are you on Mavericks?

Just upgraded. Seems to work good now. Thanks!
