Here are simplified versions of the forward- and backward-scroll speed
commands that I'm suggesting.

---------------------------------------------------------
(defun ded/org-show-next-heading-tidily ()
  "Show next entry, keeping other entries closed."
  (if (save-excursion (end-of-line) (outline-invisible-p))
      (progn (org-show-entry) (show-children))
    (outline-next-heading)
    (unless (and (bolp) (org-on-heading-p))
      (org-up-heading-safe)
      (hide-subtree)
      (error "Boundary reached"))
    (org-overview)
    (org-reveal t)
    (org-show-entry)
    (show-children)))

(defun ded/org-show-previous-heading-tidily ()
  "Show previous entry, keeping other entries closed."
  (let ((pos (point)))
    (outline-previous-heading)
    (unless (and (< (point) pos) (bolp) (org-on-heading-p))
      (goto-char pos)
      (hide-subtree)
      (error "Boundary reached"))
    (org-overview)
    (org-reveal t)
    (org-show-entry)
    (show-children)))

(setq org-use-speed-commands t)
(add-to-list 'org-speed-commands-user
             '("n" ded/org-show-next-heading-tidily))
(add-to-list 'org-speed-commands-user 
             '("p" ded/org-show-previous-heading-tidily))
---------------------------------------------------------
