@Bass: That's one of the things I like about snap view, is that it finally brings something akin to a TWM to Windows natively.  

None of the 3rd-party tools for Windows that try to emulate this concept really do a good job.  They divide up your screen into logical areas that you can maximize windows into, which is good.  But they still allow overlapping windows, they aren't built for windows that have a fixed size, and they don't even maximize natively (they take over the maximize function, but the window looks normal instead of maximized).
