MenuItem template can be improved

[van800]

I think template could be improved.
Now, if I leave everything by default, I am getting
Ignoring menu item MENUITEM because it is in no submenu!
So likely this would be better:

  public class MyEditorWindow : EditorWindow
  {
    [MenuItem("MENUITEM/MENUITEMCOMMAND")]
    private static void ShowWindow()
    {
      var window = GetWindow<erty>();
      window.titleContent = new GUIContent("TITLE");
      window.Show();
    }

    private void OnGUI()
    {
        
    }
  }
