How can I have a permanent item count in the directory view. Maybe in
the mode line or something.
I want to see how many files/directories are in the dired buffer at a glance
without keyboard cmds or other effort.

Nice exercise:
(define-minor-mode dired-count-files-mode
"*Display the number of files in the Dired mode line."
nil (:eval (format " %d files" dired-count-files)) nil
(if dired-count-files-mode
(progn
(add-hook 'dired-before-readin-hook 'dired-count-files-reset)
(add-hook 'dired-after-readin-hook 'dired-count-files-total))
(progn
(remove-hook 'dired-before-readin-hook 'dired-count-files-reset)
(remove-hook 'dired-after-readin-hook 'dired-count-files-total))))
(defvar dired-count-files 0
"The number of files in the Dired buffer.")
(defun dired-count-files-reset ()
(set (make-local-variable 'dired-count-files) 0))
(defun dired-count-files-total ()
(goto-char (point-min))
(search-forward-regexp dired-move-to-filename-regexp nil t)
(set (make-local-variable 'dired-count-files)
(+ dired-count-files (count-lines (line-beginning-position)
(point-max)))))
