I suggest that you use `M-x report-emacs-bug' for
such requests.  That's for enhancement requests as
well as for bug reports.  Saying it here instead
is OK for our info, but it won't be tracked, and
likely won't be followed up as an actual request.

There's no package for it.  It's a standalone
Lisp library.

If you want to try it:

At the top of that Dired+ web page you see a link
to the library, `dired+.el'.  Here's its URL:

https://www.emacswiki.org/emacs/dired%2b.el

The Download button there has this URL:

https://www.emacswiki.org/emacs/download/dired%2b.el

Just download it, byte-compile it (optional,
recommended), and load it.

To byte-compile it: `B' in Dired on its line.

To load it: `L' in Dired on its line (or the
dired+.elc line, after byte-compiling it).

To load it systematically, from your init file,
you can put the file's location in your `load-path'
and then put `(require 'dired+)' in your init file.

(Or you can build an autoloads file for it using
`update-file-autoloads', then load that from your
init file.)
