Hmm..  You can't do that by simply resizing windows?

Yes.

Because internal windows usually don't have properties.  The only
exception are window parameters.  With emacs -Q do C-x 2, then do

(set-window-parameter (window-parent) 'foo 3)

M-x transpose-windows

(window-parameter (window-parent) 'foo)

Gets me nil here so the parameter is lost.

Works here (with 'flip-windows-horizontally') as expected.  At the end
there are two tabs, one for a one window configuration and one for a
three windows one.
