In my oppinion a new feature should be included in the control panel in order to let the admin change the colors in the html5 template for background, buttons, header, footer, etc. The feature should also allow the admin to change the fonts types in case special characters (letter with diacritics) are not recognized by certain font types.
This feature should make things easier for the admins with no or little IT kowlege to customize the store front according to their brands and needs.
