Hi,

I attach window-edit.el at the end of this email.  window-edit.el
contains only one function: M-x window-edit.  

I tried to implement Drew suggestions into one single function.  
See my comments below.  Any feedback is very welcome.

I didn't use it yet.

Done.

Done.

Yes, right, fixed.

Yes.  Window configurations are now stored into a ring, so pressing `r'
twice will call back wcf2 then wcf1 if wcf1 and wcf2 were stored.  The
first config in this ring is the initial one.

Fixed.  Hence the ugly part of the defun.  I couldn't figure out how to
factorize all this a bit yet.  Suggestions welcome.

SPC will toggle the mode.  See the docstring.

Right. S-<arrow> now navigates through windows direction-wise.

Done.

Done.

Done.

Not done yet.   Don't know if this is really useful.

Fixed, even though there is room for improvement.

Done.

Done.

Fixed, but it's not an option.

Not done.  Will work on this later.  Depends on feedback about this
defun.

Good suggestion, done.

I let this to the user.

Thanks again for the detailed suggestions.  That was very helpful.  I
hope this function is closer that one might expect from window-edit.
