Before Sierra Calendar and after "defaults write com.apple.iCal IncludeDebugMenu 1" we could locate the first event of a repeating event in our calendar. This was extremely useful for deleting all linked events from without having to hunt them down one by one. This would be required if one of the events became disassociated from the rest of the repeating events because a change had been made to it, like time of day.

Has anyone figured out how to replace this removed "feature" - the debug menu?
