I think concept of shows may be a misleading one... In my case, I expected when I add some playlist to show, that the same playlist will appear in future instances of same repeatable show, which is currently not the case - meaning you must manually insert playlists to every future instance of one same show. This is not helping stations that aim to be fully automated (as well as http://dev.sourcefabric.org/browse/CC-2401), and I think such facility is crucial one and should be added in future versions.
