Hi..is it possible to not make S-TAB collapse

* Tasks...
* Something important...
* Something related to above...
* Something else not related...
* Again related...
* Related...
* Not related...
Instead of the current way:
* Tasks...
* Something important...
* Something related to above...
* Something else not related...
* Again related...
* Related...
* Not related...
..which doesn't allow me to see the groupings
between the tasks I have. I just think grouping provides
much quicker visual feedback of the tasks/headlines and
their relations to each other.
To implement the groupings you might have a rule that
more than two empty lines between two headings will
then activate 'grouping'.
So if I have:
* Important
Blah blah
* Related
Blah blah
* Not related
This would collapse into:
* Important...
* Related...
* Not related...
Or something along those lines..is that possible to
do somehow?
Thanks..

This is something outside the direct control of Org-mode, it is
entirely done by outline-mode. Looking at outline.el, I see two
possibilities to address this:
1. For this first one, you need a current version of Emacs (must be
CVS, Emacs 21 does not have this). Outline has an undocumented feature
which makes it possible to relate an empty line before a heading to the
heading. So when the heading is shown, the empty line is shows along
with it. Similarly, a subtree is then defined to be before that empty
line. As I said, this is an undocumented feature in so far as the
corresponding variable is not customizable. However, you can still set
it in the old way using
(setq outline-blank-line t)
If you do it in this way, there will be no difference between a single
or a double empty line. An empty line before a heading will create an
empty line in the CONTENT and CHILDREN views of org-cycle.
2. If we insist on your convention on using two line to mark a
separation (we should, because it is the better convention), you would
have to redefine a function in outline. This is not clean, but who
gives a s*** :-) And I like this convention better, because I very
often want to have an empty line above a headline without it meaning a
separation.
The function to modify is outline-show-heading, and it must be modified
after outline.el has been loaded. If you are only using outline in
connection with Org-mode, here is a way to do this:
(add-hook 'org-load-hook
(lambda ()
(defun outline-show-heading ()
"Show the current heading and move to its end."
(outline-flag-region
(- (point)
(cond
((bobp) 0)
((equal (buffer-substring
(max (point-min) (- (point) 3)) (point))
"\n\n\n")
2)
(t 1)))
(progn (outline-end-of-heading) (point))
nil))))
If you want this for other uses of outline as well, you could use
`eval-after-load' or defadvice to achieve this change.
There is a small possibility that doing either of these things might
break something else in org-mode. I don't think so, but maybe I am not
overseeing it fully. If you see something strange, let me know.
Hope this helps.
