Ah, thanks. I could swear that I've never noticed the red icon. But it is not part of the macOS version, correct?
EDIT:
I think I got it: It was possible to uncheck "Doctor Who" in General->Features prior to .70 and it still is in the macOS version (so the icon does not appear in under the Playlist node). Windows version changed in a way that the checkbox has been removed from General->Features and "Doctor Who" is now a mandatory item in "Playlists". If you update the macOS version, please leave this as an optional feature and try to promote it in a less intrusive way.
