I would really like to be able to add Discover shows / movies to playlists. The current Watchlist is fine I guess, but I’d like more control over splitting it up into user-defined categories. For example, shows I’m currently watching, movies coming soon, stuff I’m interested in for when I want to watch something new later…
Playlists would be better, too. For example, I could add a playlist for the various Arrowverse shows in air order — which would actually be very handy for me, as in Australia the shows are all actually on different streaming services.
I realize playlists would seem impossible, as you can’t really auto-start a different item (let alone one from a different streaming service) after one finishes, but even if I have to go back to Plex and manually select the next one, it’s still so much better than having to swap between apps and re-find the media I’m looking for every time.
