Hi there,
Would it be possible to allow sorting smart playlists’ episodes by airdate?
The wiki suggests the field is available for episodes (shttp://kodi.wiki/view/Smart_playlists) but it doesn’t appear as a sorting option.
I’m trying to achieve the same as the people asking for TV Show sets. I’m my case, I want to get the Arrow, Flash, Supergirl and Legends in the right order so I don’t stuff up the crossovers. 
I wonder if making airdate an option on smart playlists is an easier option than adding sets as a TV show functionality, as we are already 99℅ there: currently I have a smart list with the relevant shows sorted by date added. It works most of the time as normally I add the episodes to my library in the same order as they come out but not always, hence the request.
Thanks,
V
