Maybe look at Browser>>buildWith: or all the other buildWith: implementations? No need to subclass DictionaryInspector, I'd simply subclass Model. You would have two lists, and a text pane. Your model will have to provide methods to get the list and get/set the current index. E.g. #lessonList, #lessonListIndex, #lessonListIndex: and #sectionList, #sectionListIndex, #sectionListIndex:. When you select something in the lesson list, #lessonListIndex: will be sent. In response, you would send "self changed: #sectionList" which will cause the section list to be updated.
