I did not know that, on Windows 7 systems with a dual-monitor setup, you can middle-click on a window title bar (maximized or normal) and the window will instantly jump to the other monitor. To return it, simply middle-click the title bar again.

Huh.

Edit: Turns out I’m a complete git and the reason I didn’t know about this is because it isn’t a feature of Windows 7 — it’s actually a feature of DisplayFusion. D’oh!
