 The script [`UIManager.cs`](https://github.com/Unity-Technologies/arfoundation-demos/blob/master/Assets/UX/Scripts/UIManager.cs) is used to configure the Instructional Goals, secondary instructional goals and holds references to the different trackable managers.

+UIManager manages a [queue](https://github.com/Unity-Technologies/arfoundation-demos/blob/master/Assets/UX/Scripts/UIManager.cs#L120) of [`UXHandle`](https://github.com/Unity-Technologies/arfoundation-demos/blob/master/Assets/UX/Scripts/UIManager.cs#L6-L16) which allows any instructional UI with any goal to be dynamically added at runtime. To do this you can store a reference to the UIManager and call `AddToQueue()` passing in a UXHandle object. For testing purposes to visualize every UI video I use the following setup.
+
+```
+m_UIManager = GetComponent<UIManager>();      
+m_UIManager.AddToQueue(new UXHandle(UIManager.InstructionUI.CrossPlatformFindAPlane, UIManager.InstructionGoals.PlacedAnObject));
+m_UIManager.AddToQueue(new UXHandle(UIManager.InstructionUI.FindABody, UIManager.InstructionGoals.PlacedAnObject));
+m_UIManager.AddToQueue(new UXHandle(UIManager.InstructionUI.FindAFace, UIManager.InstructionGoals.PlacedAnObject));
+m_UIManager.AddToQueue(new UXHandle(UIManager.InstructionUI.FindAnImage, UIManager.InstructionGoals.PlacedAnObject));
+m_UIManager.AddToQueue(new UXHandle(UIManager.InstructionUI.FindAnObject, UIManager.InstructionGoals.PlacedAnObject));
+m_UIManager.AddToQueue(new UXHandle(UIManager.InstructionUI.ARKitCoachingOverlay, UIManager.InstructionGoals.PlacedAnObject));
+```

 There's a [`m_CoachingOverlayFallback`](https://github.com/Unity-Technologies/arfoundation-demos/blob/master/Assets/UX/Scripts/UIManager.cs#L76) used in order to enable the ARKit coaching overlay on supported devices but fall back to Cross Platform Find a Plane when it is not. 

 The script [`ARUXAnimationManager.cs`](https://github.com/Unity-Technologies/arfoundation-demos/blob/master/Assets/UX/Scripts/ARUXAnimationManager.cs) holds references to all the videos, controls all the logic for fading the UI in and out, managing the video swapping and swapping the associated text with each video / UI.
