+    Demo - Save previously entered strings for Input and Combo elements by using user_settings calls
+
+    This demo is the same as the Demo_User_Settings_Remember_Input_and_Combo.py
+    The difference between the 2 files is that this one users the UserSettings class syntax while the other uses the function calls.
