Least advertised golden nugget in Mac OS X Lion

I can’t help but blog about this even though it is not about the main topic of my blog which is virtualization. This one feature in the latest version of Mac OS X was something I have always wanted being spoiled by the Windows OS. What is it? Now you can hover over any corner of an application window and resize the window. This is not some revolutionary thing but I will use it more than I will probably use Mission Control. Thanks Apple.
