+* `.startSubwindow(name, title=None, modal=False, transient=False, blocking=False)` & `.stopSubwindow()`  
     Used to start and stop defining a *SubWindow*  
     Setting a `title` will override the `name` as a title for the *SubWindow*.   
     Setting `modal` to True, will prevent the user from interacting with the parent window until the *SubWindow* is closed.  
+    Setting `transient` to True, will cause the *SubWindow* to respond to parent window events such as hide & show.  
+    Setting `blocking` to True, will stop execution of your code once the *SubWindow* is shown, until the user closes it.  
 
 * `.openSubWindow(title)`  
     Used to reopen the named *SubWindow*.
