The Character Manager allows you to add and delete characters, and also to attach associated information to each character.
Point of View can be (very simplistically) defined as the stance from which a narrative–or part of one–is told. The point of view can be focalized in a character or a narrator. And it can change from chapter to chapter, or scene to scene, or even paragraph to paragraph.
The POV ELEMENTS tab of the Character Manager show all the discourse elements told from this specific character's point of view.
