My point is that it’s actually explained in the introductory information for using the application available from your dashboard (Help > Knowledge Guide). The designers understood that the tool needs explanation, so they provided it. Could they have done it better? Maybe. That said, I understand that these things aren’t straightforward and they’ve been tweaking the dashboard / layout for years.
