Another way to maintain continuity for various viewpoints is to cut and paste relevant scenes into a separate document so you can read them in sequence. That way you don’t have to dig through anything in between to make sure there’s a logical flow to what they’re doing.
I don’t always write scenes in sequence, but skip around. Since it’s important to keep the flow of the story going in the proper order, I find this is helpful to maintain character development within the story. Characters should change and evolve, and by having all their action in a single document makes it easier to see the story through their eyes and how their motivation or attitude might change.
