Mariner Software StoryMill for Mac - Manual (Page 27)

Storylines
The timeline shows the chronological order of your scenes
(regardless of narrative order). Within the broader timeline, you
can then group scenes into storylines. This allows you to logically
group scenes which would otherwise overlap:
You can change or assign a sceneʼs storyline,by visiting the
metadata pane in the sceneʼs view window, or by editing the scene
in the timeline view.
To add and remove storylines, use the + and - buttons at the bottom
of the storyline pane. Double click a storyline to rename it.
Drag and drop storylines in the storyline pane to reorder them.
When you move a storyline, all scenes associated with it will be
moved vertically in the timeline as well.
Drag the bar between the storylines pane and the timeline to resize
the storylines pane.

Tip:
Changing the zoom level of the
timeline does not affect storylines
because it only affects how much
time is shown (which is horizontal).
