Sorry, just have to vent (and did to features request). This seems like it should be a pretty basic preference setting. I've been trying to figure this out since switching from PC in December. Thanks - at least your post allows me to stop looking.
The only other thing I miss is being able to resize a window from any corner or side as opposed to just the bottom right. The spaces feature makes up for it most of the time, but when I'm plugged into a larger monitor it would still be nice.
