+Collection view
+: The collection view shows hierarchical list of all game objects and components currently instantiated in the game and from which collection they originate. This is a very useful tool when you need to dig into and understand what you have instanced in your game at any given time and from where the objects originate.

+Resources view
+: The resources view shows all resources currently loaded into memory, their size and the number of references to each resource. This is useful when optimizing memory usage in your application when you need to understand what is loaded into memory at any given time.
