My idea is not about windows, though.  It's about a workflow that resembles
searches: you keep searching for the same or similar strings as long as you
are interested in a particular string/regexp; as long as you do that, using
"C-s C-s" to repeat search, perhaps with minor edits of the search string,
is what you want.  Then, when you want another search, you discard the
previous search string and start with a completely new one.

I do that sometimes, not to rarely to remember it as a feature.  That's why
I suggested an explicit command, because I don't think Emacs can guess my
intentions in this case.
