This question already has an answer here:
Is there a hidden setting or an external utility that would enable moving windows on Windows like on GNOME?
I'm particularly thinking of moving windows using Alt + Drag and drop (which can be changed to Win + drag and drop).
I have machine with Windows (7) and two big monitors at work, and I tend to use multiple smaller windows. Moving them quickly around is essential, so I'm always missing this GNOME feature.
