We identified that the Timeline should be able to generate a timeline with text, image, and/or videos. It would also be able to section off the items, e.g. by season or by the year of the event, have custom titles and season/episode association for each item.

When the new section is added, the association would automatically be set to the next episode, which reduces the mistake of making a duplicate or skipping ahead of episodes. If the producer chooses, she can change the episode to whichever she wants.
