It's years ago (2008 or 2009). I don't know whether there was a thread about 
it or whether there was IRC discussion or bug reports.

The problems with the non natural layouts are various, e.g.:
* windows might get too small as all windows have same size
* windows might move to a bad position, e.g. a window from the top left goes 
to bottom right

The natural layout tries to optimize that by using an algorithm using size and 
position as reference. The downside is that the layout might appear to be 
random. But so would a movement all across the screen look random.

It needs a full rewrite no matter what :-)
