Thanks for responding. I meant specifically the :: syntax with org IDs, and
not filenames. I did confirm that this feature is currently only in Doom
Emacs, see:
https://github.com/doomemacs/doomemacs/blob/master/modules/lang/org/config.el#L639-L659
Regarding org-export-with-broken-links, is there a way to export the text
of the link, and not kill all the text?
