    // AddControlParameterCommand itself launch the dialog and allow the user to
    // edit the parameters before ever adding it to the list at all.  That would
    // be a lot cleaner, but it would also require going against the flow of how
    // this logic always worked, so it would require a lot more thought to
    // achieve the same end result that way.  Instead, I just used this hack
    // overloaded slotUpdate() to tell it when a new controller was added, so we
    // could grab it here and launch the dialog on the generic blah we just added
    // to the list right before this slot got called with the optional bool set
    // true.
