Timeline feature

For series it would be great with a timeline feature that include:
- The ability to create a timeline relevant for your book/series.
- Connect character descriptions to the timeline so that a character can develop over time.
- Connect descriptions of world building objects to the timeline so they can develop over time.
- Connect books, or even chapters to a position in the timeline.

The purpose is for the AI to be able collect the correct character and worldbuilding information automatically dependent on where in the timeline the chapter takes place.
Perhaps you also can allow for the scene “extra instructions” to place a single scene at a specific place in the timeline.
