In my novels, there are several time jumps. Usual ones like "The next day", "A few hours later", ... Sometimes I have flashbacks and sometimes two scenes happen at once.
First, it would be super awesome to have a feature in "Plan" mode, where I can arrange scenes in a timeline. This would be super helpful for outlining a story and avoid plot-holes.
Secondly, it would be cool, if this timeframe could get some properties (like season, weather or day/night) and be stored with the scene (kind of like the POV). So when I generate the prose it doesn't say "the summer sun was warm", when it happens in winter.
I know, that's a big one, but it would help a lot in crafting a novel.
