Just imagine your tiling partition consists of two windows, one on the
left and other on the right. I want to be able to switch them, just as
you describe later :P

I realised about the show-all-children function but it has no
effect. Also I tried with frame-raise/lower-child, but it only works
when on tile-left/right/...-layout. If I'm on one-column, tile, etc,
it will do nothing, but I don't understand why :(
What am I doing wrong?
