Just out of curiosity, where?

I don't have anything aginast flattening list, but the problem is that
when you are using it, it means that you are finding a window's first
live descendent.  Like you said about 2 weeks ago, this is not ideal, as
you are splitting window A with C, when they are not siblings.
___________
|     |  C |
|  A  |----|
|     |  B |
|_____|____|

This approach will have to be used  in the split top level siblings approach.
