Indeed, but maybe a Settings preference for this would be welcome, rather than just assuming everyone is on a single-screen laptop.  I’d love to be able to show quicktime full screen on one monitor, while grading projects on the other screen – it’s possible with Quick Look so why not make that the universal behavior?
