There used to be a 'tile windows' since windows 2.0 or something like that, but it did just that, splatted the windows to take up all the space.
One thing I like about X11 and Windows doesn't do it, is alt-dragging from anywhere in the window, last time I used Windows you couldn't move things around by holding alt and left clicking anywhere, you could only do that from the title bar, which means you can't slide the top of the window off the screen.
The other major thing for me is selection copy, if you highlight text, you can't middle mouse button to paste it, you have to ctrl-c first, which is just more steps.
