a date when an image will expire and be removed from the playlist.
Expiration date for Media is already implemented, here is the original suggestion: http://support.yodeck.com/forums/301815-general/suggestions/17696950-asset-expiration
This however does not remove Media from Playlists. There might be a need to remove expired Media from Playlists without deleting it. So, I am leave this to be reviewed and to gather more traction.
