Hi Nicolas,
Ah yes, I remember when I was exporting to HTML and would have
both properties. Thank you.
Also, I think I will stick with ID purely because I want links which
span multiple org mode files.
I also plan to learn some more Emacs Lisp to make this link creation
thing a bit easier. I know there's been efforts to get org to behave a lot
like a Wiki (which I think it already does):
https://orgmode.org/worg/org-blog-wiki.html
I'd like to mess with Helm and get a custom helm source. org-insert-link
can already use Helm, but it could be improved a bit.
* Show the IDs (*and* headings :-) of recently created links (because you
know,
the IDs are hash codes (grumble grumble). Currently Helm just shows the
IDs :-(
* Show a second Helm list of headings (perhaps all headings in org-mode
files)
- If heading already has an ID, then simply use that ID.
* Provide a context menu, where you can choose to create an ID
- Provide a mini buffer to *specify* an ID (evil laugh). Default action
will
create an ID
Thanks,
--Nate
