Tweak design defaults based on user interaction observations. It seems that people don't like to play around with the settings to see what different options are exposed as they play around, so set the defaults to a position where one of the best features - custom icon colors - is visible immediately. For those who haven't noticed, the QuickShare design settings are designed to be played around with until the user finds their favorite configuration. And there isn't really a way to "break" anything from this screen.
