Somewhere on the forum I read that you can set a backButton property for the navigationBar component. This is handy, cause I wanted to give the backButton a different theme and look then the navbar on the basis of what view is pushed. It works nice when I add this property outside Architect (TextMate). But, because there is no such property in the config inspector in Architect, each time saving in Architect will overwrite the custom stuff added outside Architect. Is there a way to add this property for Architect, or do I use a private feature?
