I'm not seeing this ability in the Logo Playlist.
Have you found it yet?
Turn "show crystal" off in the Program Settings, and then open the Logo Playlist panel. Presto! It warns you that the crystal isn't going to be shown unless you (click here) turn it on.
If "show crystal" is on, there's no need to say anything in the Logo Playlist panel, so you can't see it.
Rather elegant implementation.
