One operation of ECB is to make the editor area comprise the entire
frame and revert that operation to make view windows visible again.
This can be done on-the-fly with `clone-window-configuration'.

The major problem with window configurations "created from scratch" is
that you have to devise that configuration first, memorize it, and
eventually recall it.  Personally, I prefer an approach where I can
change the layout of windows in an ad hoc manner without having to
resort to predefined configurations frequently.

I thought about using the layout engine provided by ECB.
