I also recommend that the ability to play a YouTube Playlist also contain the ability to automatically refresh when new content has been added to the YouTube Playlist. I have been testing out several digital signage solutions over the past month and they ALL have this ability. Yodeck is the only platform I have found that does not support this function.

Or at the very least allow the administrator/creator of content to set a refreshing time so the URL is reloaded and/or content re-downloaded...depending on how you code this function to work with the player on the Rasberry Pi.

This is a great suggestion. I wish this feature was available.
