Give a collection one concrete purpose
The publisher describes Watchlist for all members and Crunchylists for Premium members, with up to ten lists of one hundred shows each. A useful distinction is between remembering that a show exists and planning a sequence. An ordinary saved-title queue is sufficient for the first task; a named list that you can reorder is more useful for the second.
Build a plan without claiming it changes episode order
For example, create one collection for older series you want to finish before returning to current releases. Add the relevant shows and order them according to your own plan. The help describes rearranging shows in a Crunchylist, not changing the publisher’s episode order inside a series or creating a continuous licensed compilation. Keep that scope clear when sharing your viewing plan with someone else.
Use the list controls rather than restarting playback
The documented web route opens lists from the avatar menu; mobile uses My Lists with separate tabs. The help also describes renaming and deleting Crunchylists, removing finished shows and applying filters. Those organisation actions do not require marking an entire series watched simply to move it out of a plan. If a list appears absent, first check which list tab and account you opened. The source was retrieved through the publisher’s indexed help text; no paid feature or account operation was tested.
