Currently it is possible on Plex clients to start playing music then go to photos and play a slideshow while the music keeps playing. This creates a nice scene/multimedia slideshow.
It would be nice to save all the selections that were made to create this scene/multimedia slideshow. For example the music that was selected (playlist, artist, genre, collection etc.) whether shuffle was selected. For the pictures, the photo search or folder that was selected and whether shuffle was selected.
This way the same scene/multimedia slideshow could be played later easily without having to go through all the selections again especially for someone else wants to replay that experience who may not know all the selections that were originally involved.
