It would have an endless number of movable, and linkable tabs.
It would have a map that linked to all geographical references, and a timeline that auto-populated from references to the passage of time.
When you made a change, it would generate pop-up questions, like “What about the preceding scene with this character made them act like this?” or “How does this affect their role in the climax scene?”
It would have picture files to represent common scenes, for consistent blocking purposes.
It would be able to form graphs and pie charts at the press of a button that represent rising and falling action, character arcs as they change, and a scatter plot of the level of tension at any point in the novel.
Something tells me this is what brain power is for, but I’ll keep hoping for a faery godmother to grant me this magic tool.
