One cool thing I like about Windows 7 is that when you drag a window to the top of the screen, it automatically full-sizes the window for you. This would be really useful for me in OS X...any way to get this to work?
I remember reading about a simple program that could do this. I don't remember it's name or even where I read about it. I do know that it didn't work with every app and liked to crash. Also, it was written in Applescript.
I use Better Touch Tool and find the window resizing works very well. You can also get half screen windows dragging to left or right. Also great (and it's primary purpose) for adding gesture functionality to the trackpad and/or Magic Mouse. And best of all, it's free!
