This goodie is also known as the “Diving” inspector as it allows you to navigate through an object structure by following each variable on a double-click. The inspection depth is shown in the inspector just above the “self”. You climb up the structure by clicking on that list item. Once loaded into your image, it takes over the standard inspector but uses any dedicated inspector as its model (e.g. EtDictionaryInspector). To see that working, try inspecting “Array with: Smalltalk”.
