Im wondering if anyone can point me in the direction of how to create a plugin with add-ons. It looks like the approach is first to create a plugin with the core feature, and then write other plugins that interact with the main plugin. But for some reason its impossible to google, as all my queries brings out plugins from wordpress.org, feather than how-to's and tutorials. So i was hoping someone here could explain or point me in the direction of a guide.
Thanks!
