 You can set enter, default and exit translation for every view in intro activity. To achive this you need to get translation wrapper for chosen view (for example: ```getNextButtonTranslationWrapper()```) and set there new class which will implement ```IViewTranslation```
 ```java
-getNextButtonTranslationWrapper()
+getBackButtonTranslationWrapper()
                 .setEnterTranslation(new IViewTranslation() {
                     @Override
