Thanks for the reply. Strange to announce the new functionality and not have any sample code, don't you think? Perhaps you can pass on the feedback that it would be good to do that next time. Thanks again.
No, we do not have any sample code specific to the new Lists functionality at this point in time. However, we're updating our samples and documentation all the time, so keep a watch on our blog and github (github.com/alexa) for updates.
