If a story alternates narrators or limited perspectives, authors need to inspect that sequence across the actual sections where it happens.
A character list is not enough
You can describe a character perfectly and still lose control of viewpoint across a long manuscript. The problem appears in sequence: three chapters in one perspective, an accidental switch inside a scene, or a character who disappears for eighty pages.
POV belongs to sections
B-Maker can assign a narrator and narrative perspective to manuscript sections, including limited perspective, omniscient narrator and external observer. Child sections can inherit POV when that is the intended structure.
A POV stream changes the question
Normal manuscript order asks “what comes next in the book?” A POV stream asks “what does this character experience across the book?” Opening that stream lets you inspect only the relevant sections while preserving the real manuscript order.
Why this matters during revision
It becomes easier to see whether one narrator has enough continuity, whether knowledge leaks between viewpoints, and whether a character arc still makes sense when read only through the scenes that belong to that perspective.
When you do not need it
A single-narrator book may need no explicit POV management at all. The feature earns its place when perspective itself becomes a structural dimension of the manuscript.
Read the book in the dimension you are revising.
POV tracking keeps narrative perspective connected to real manuscript sections instead of a separate spreadsheet.
