The Project Hierarchy window is a multi-purpose window that allows you to do the following:

Event Manager

Add/rename/remove events in the event list.

Runtime Parameters

Gives quick access to the Runtime Parameters in the project. Everything you can do in the Runtime Parameters window, can also be done here.

Scenes

All the SoundMaker components will live under a scene. You can have multiple scenes in a project. These individual scenes will get exported as FPKs.
