Calendar option to hide unstarted watchlisted series episodes

Show watchlisted upcoming series in Calendar without showing unstarted existing series

Add a Calendar option that distinguishes between watchlisted shows that haven't premiered yet and existing shows on the Watchlist that haven't been started watching. The ideal Calendar would:

• Show episodes from series already being watched.

• Show premieres of upcoming/new series added to the Watchlist so their debuts aren't missed.

• Hide episodes from existing series added to the Watchlist but not started.

For example, adding an upcoming series to the Watchlist before it premieres should make its premiere appear on the Calendar, but adding an older series with multiple seasons to the Watchlist as a someday-watch should not clutter the Calendar with its currently airing episodes before the series has actually been started.

The exact implementation could vary: Trakt could distinguish between shows based on whether they have aired their series premiere yet, whether the user has watched any episodes, or another approach that produces this behavior, or just show series (or season) premieres for watchlisted shows in the calendar, or make it a setting.

Rationale: a Watchlist represents intent to watch someday, while continue watching / history represents something actively followed. Treating those the same in the Calendar creates noise and makes it hard to track upcoming things that matter, while completely hiding Watchlist items would lose one of the most useful reasons to add an upcoming series to a Watchlist: knowing when something anticipated finally premieres. This would let the Calendar focus on shows actively watched plus upcoming shows being waited for, without filling it with episodes from backlog shows not started.
