Pros: A few things are changed. For one, it is much easier to edit the main window background color.
Cons: Who likes yellow as the default background color? Ick!
Other Thoughts: Run the app first and save the text preferences. Then, edit the text file and make this change:
MainWindowBackground = #80ffffff
Now, the main window has a white background color. Apparently, the color value is a six character hex code with 80 to the left of it.
