Currently it's only planned to let the buffers stay alive. I dunno if I
can save a buffer showing arbitrary widgets? I guess I would have to
create the widget view from an internal representation, preferably in
the format of a "find" call or the s-exp format used by find-cmd.
What I want to have is an export to these formats so that you can save
the results in these forms. I guess the reverse should not be too hard.

Another advantage is that it can help you to remember what you have
forgotten. I for example repeatedly forget that e.g. for
-ctime n File's status was last changed n*24 hours ago. See the
comments for -atime to under‐ stand how rounding affects
the interpretation of file status change times.
what I want is
-n for less than n,
e.g. -ctime -1 for "status changed since last day" but I tend to try
with -ctime 1 and wonder why it fails until I remember that I need "-".
With the widget based version I can force the user to think about the
sign by making it mandatory (with a reasonable default).

`lazy' is perfect. AFAIU `repeat' won't do since the syntax of "find"
is actually recursive, so there is no way to avoid recursive widgets.
Thanks,
