[O] Org-Brain: Second level headline?

[Sven Bretfeld]

Hi

I'm not sure if I misunderstood a feature or if this is a bug or setup
problem. In org-brain one has two possibilities to create new children
to a node:

1. org-brain-add-child (f) --> creates a new org-file
2. org-brain-new-child (h) --> creates a new headline

The problem is that only 1st-level headlines are shown in
org-brain-visualize. Shouldn't all headline levels be visualized?

Example:

>From a file called Software.org, looking like this:

,---- Software.org
| #+BRAIN_PARENTS: Manuals
|
| * Emacs
| ** org-mode
| ** AucTeX
| * Gimp
| * Vivaldi
`----

org-brain-visualize shows (as expected):

,----
| Manuals
| |
| ▽
| Software
|
| Emacs  Gimp  Vivaldi
`----

The word Emacs should be a node showing the children "org-mode" and
"AucTeX". But it shows only its parent and siblings when clicked, no
children become visible:

,----
|          +-Gimp
| Software-+-Vivaldi
| |
| ▽
| Emacs
`----

Org-Brain would be great for organizing the writing process of article
and book projects etc. The final text could gradually grow out from
mindmap'ish structures. But org-brain's multiple-files approach goes
against it. You can't export an article from hundreds of org files, can
you? So it should be possible to organize a complex "brain" (the
article-to-be) in a single file with several headline levels
(representing the network of information from which the text-body will
gradually grow).

Thanks to the developer. Great piece of software and a fantastic idea.
