excalibur VS org-special-block-extras

have not tried it, but this has been in my bookmarks a while: https://github.com/camelot-dev/excalibur

Not sure it lets you draw the columns but you could give Excalibur a look maybe? https://github.com/camelot-dev/excalibur

I'm guessing since this is mostly a non-commercial effort there's this library you could try, https://github.com/camelot-dev/excalibur and see if it helps.

Emphasis syntax is currently fixed. There is https://github.com/alhassy/org-special-block-extras/ though. And there were discussions about custom markup elements.

I've been using org-special-block-extras to insert special blocks in org-mode which I then export to PDF through LaTeX, things such as margin notes or colored blocks.

This, among other things, is part of the v4 release of org-special-block-extras ---sadly I haven't yet gotten around to making a proper changelog or updating existing docs.

I opened an issue on github btw.

This is very similar to org-special-block-extras' doc feature, where one "documents" something in an associated file and the documentation is shown in a tooltip in Emacs and in a tooltip in HTML export and in a glossary in LaTeX export. But yours seems to be much more sophisticated by linking implicitly, whereas this requires an explicit link. Way to go ;-)

I'm excited to announced that version 2 of org-special-block-extras is out :-)

Thanks for the links tdehaeze :-) When I replied to you earlier, it didn't occur to me to just actually use the `defblock` mechanism to do what you wanted. A ~3line implementation that works well for me can be found here: https://github.com/alhassy/org-special-block-extras#Installation-Instructions. All the best!
