+    Program that is used to create new themes for use with PySimpleGUI's "Look and Feel" settings.
+    You are presented with a grid of mini-windows that is created for color palettes downloaded from https://colorhunt.co/palettes
+    The file color_themes.py contains a large dictionary of approx 1780 palettes.
+    
+    For each palette you are shown 4 candidate themes, 2 "light" and 2 "dark".  The window shows 5 palettes so you'll have a
+    total of 20 candidate themes displayed in total. 
+    Each candidate theme has a 3 options - The button color (text and background), the text color for Input/Multiline elements,
+    and the name of the theme when you save it.  These you choose using the radio buttons and one input field.
+    To "save" one of these candidate themes, check the checkbox to the left of the layout, choose the radio buttons for button
+    & text settings and optionally change the theme name that is shown above the grid of OK buttons.  By default the name starts
+    with either "Dark" or "Light" and is followed by the first 2 "tags" that were posted with the palette on the colorhunt site.     
+    
+    After you've selected the themes you want to save from the window of 20 click any "OK" button in the window or close the 
+    window with the "X".  You will see the dictionary text in the Debug Window and the values will also be written to a file.
+    You'll then be shown the next group of 20 candidate themes.
+    
+    If you want to exit the program entirely, click any "Cancel" button the page.  Note - cliicking "Cancel" will not save any
+    theme you have checked with the checkbox.  You should only exit from a window you have not selected any themes for saving    
+        
+    If a Theme is selected for saving, then the values for the LOOK_AND_FEEL dictionary are displayed in a debug window and are 
+    also appended to the file new_theme_dict.py.  You will need to edit the new_theme_dict.py file to get the syntax correct.
+    A "," or "}" may need to be added in order to make the table be correct.
+    
+    If you're using this program it's assumed you know what you're doing and understand the LOOK_AND_FEEL dictionary and can 
+    figure out how to get the syntax correct for adding it to the main dictionary of themes.
