I would really like to make it so it's like the iOS 7 keyboard, maybe completely black with white text, or just theme the close and delete buttons. How would I set this up in Winterboard folder structure wise?

I know that these are the images I'm looking at and they're located under:
Library/PreferenceBundles/exKeySettings.bundle/
And there are additional plists, but as far as I can tell, they are not related to the display of the keyboard, but rather the settings page itself.
