The diplomacy feature in the organization template has the toggle to show all relationships of the organization in the article, but there is no option to hide individual ones. I propose to add an option to set relationship as private. That would allow to prevent accidental spoilers for readers and/or players in articles.
I think an option to hide them fully, or to mark them "anonymous" as a seed of mystery for players could be VERY cool! Maybe with some subscriber group controls? Just some ideas.
