This is great. Just what I needed. Thanks so much for taking the time out to explain.
I’ve managed to glob the files from the plugin subdirectory and serve the list as JSON accessible from the browser. I’d like the AJAX call to fire when the user opens their preferences. There’s a combo-box ready and waiting but I still don’t get how the app knows when to trigger the call. Do I need to extend the ‘RestrictedUserRoute’ in the controller? how does the app know that this particular controller is linked to that plugin outlet?
