allow narrators to rearrange scenes
In one of the games I'm playing, the end time of the last scene (let's call it Scene 4 to make this easier to follow) is "Day 3, 10am". But one character was not present for either of those scenes - the last scene this character was in was Scene 2. Originally, Scene 5 was going to feature all three characters at Day 3, 11am, but then the narrator and player decided to have another scene with just them - that would take place at Day 3, 2am - right after Scene 2. It would be really handy for readability of the finished game/chapter if the narrator could change Scene 5 to be Scene 3 (and 3 to 4, 4 to 5).
