In this session, we talk about opting out of actions so that only relevant actions are available to the user. We also show how to place Global actions in sub-menus to build a complete menu bar. Furthermore, we explain Class Constraints and how they can be used to make the user aware of the rules they should obey. We also show the concept of DefaultStringRepresentation of objects.

To make your experience smooth, we set the main tags mentioned in the video in the right-bar menu of this mini-player. Choose an interesting subtitle from the list and immediately get to the exact place of the theme navigation item in the video. Now you can pick any topic on which to be instructed without watching the whole video.
