I have three more planned for the moment. 1. Adding nested comments 2. Activity Feed 3. ActionCable tie-ins The activity feeds and ActionCable ones will probably come out in December. If there is interest, I've been thinking about also doing an episode of taking a Bootstrap "Theme" and showing how to incorporate it within the application.
