Make the list useful to you
Open any film or series and select Save to My List. Return to My List when you are ready to choose. A second press on the saved button removes the title; it does not affect the catalogue.
Record the episode you finished
A series page with recorded seasons includes a checkpoint form. Select the season and enter the last completed episode. That distinction matters: if you finished episode three, save three rather than the episode you intend to start next.
Checkpoints are manual notes in this browser. They do not listen to a player or track how many minutes you watched. You can clear a note from the same series page when you begin a rewatch.
Backup and merge
Use Create backup on My List and copy the complete text into a note you keep. In another browser, paste it into Restore backup and select Merge backup. Known saved titles are combined, duplicates are ignored and an existing checkpoint is kept when both browsers have one for the same show.
The tool reports unreadable backups instead of guessing what a damaged file meant. Keep the full text, including its opening and closing braces. Back up before clearing website storage or replacing a device.
