Strange, I have a message in the archive from 24 Sep,
but it doesn't exist on the thread that you posted.

I suggested to use TAB that goes to the next file
and wraps around at boundaries. Then '>' could be
reused to go to the last file.

Maybe then like there is a user option `ls-lisp-dirs-first'
for ls-lisp.el, a similar option should be added to dired as well,
so users won't need to manually add "--group-directories-first"
to `dired-listing-switches'. Do you agree?
