The Main view
The right-hand pane of the Memory Profiler window shows different views of the currently opened snapshot data.
The toolbar above it contains a drop-down menu that lets you choose different ways to represent snapshot data in the Main view. Choose between Tree Map, Memory Map, and various types of Table views.
Next to the view drop-down are two arrow buttons that allow you to go backward and forwards in the view history. So if, for example, you follow references through a chain of referencing objects, those arrows allow you to return to previous views quickly, much like a browser back button.
The Load View... button will open a dialog to import a custom view defined in an XML file.
