     Demo showing how to remove the titlebar and replace with your own
     Unlike previous demos that lacked a titlebar, this one provides a way for you
     to "minimize" your window that does not have a titlebar.  This is done by faking
     the window using a hidden window that is minimized.
-    
+   
-    While this demo uses the button colors for the titlebar color, you can use anything you want.
+    The DarkGrey8 is already a theme in PySimpleGUI.  It's here to show you how to add your own and have it them
-    If possible it could be good to use combinations that are known to match like the input element colors
+    be used by your Custom Titlebar. 
-    or the button colors.

-    This code eventually grew into the internal implementation of the Titlebar element.  It's a good example
-    of how user code is just as powerful as internal PySimpleGUI code.
