If I make a custom filter, is it possible to save it as a playlist?
It will not be editable ( as far as changing filter choices) after saving as playlist. but yes you can save it to a playlist. it will be a smart playlist so anything else that is added to library later that fits the custom filter/sort will be automatically added to playlist.
this is me making a playlist of the DC Tv shows by unwatched in release date order. When i finish watching an episode it will be removed from playlist and new episodes will be automatically added in release order.
Great, should be possible in the future to have also the saving feature for the custom filters ?
