The Kirby Linked Pages try to “synchronize” relations between pages so you can edit a relation on each linked pages.
It simply uses structures with a page field and add information to the target page on save.
As I’m not an engineer, the actual logic to setup the plugin is not simple, so any advice will be appreciated
