When Tundra is started without any command line arguments, the default/dummy scene, which is created e.g. when --file or --server command line argument is used, is not created. Because of this, it's not possible to open the Scene Structure window for creating any content. User can import still scene by drag-and-dropping, but menu items would feel more intuitive. In case where we already have an existing scene, and these functionalities are used, a modal warning dialog should be shown to inform the user that the action he is going to perform does not save any modifications to the current scene.
