In addition to a linear timeline (which would also be great to have), I’d love a 2D storyboard tool for visualizing and organizing chapters/scenes. Instead of just arranging scenes chronologically, this would allow me to place scenes as “bricks” on a canvas and draw lines between them to indicate different types of relationships (such as cause-and-effect, callbacks or thematic links). Being able to click on a scene to view its content, and easily see how many scenes reference a specific event or element, would be extremely helpful, especially for tracking redundancies or complex narrative threads. A visual, non-linear map would make managing intricate stories much easier.
