Plugin/Application development

Thanks for your reply. Do you know where I can get more information on how to implement these interfaces as there isn't enough information in the documentation?

I was going to suggest reviewing the developer training for creating custom applications, and I noticed this code is that document's attached sample. This is a great starting place. Just to note, while this example doesn't implement all the items that an application can (and should), it should still already be functional. It won't support being managed within a group (via group > applications > add application), but you can still enable the application site-wide in Administration > Applications and then add the widget to a page to call the APIs the application exposes.

As for other functionality, it's a matter of picking and choosing what kind of functionality you'd like to expose with the application.

If you can share a bit on what you'd like to do, I can hopefully point you to some specifics.
