Tommy E. Scrivener has no links between scenes and characters, locations, tags nor items. Furthermore it has no strands nor a chronological view. I'm not saying Scrivener is a bad tool, but for me the benefits of Storybook are clearly predominate. In Scrivener it will never be possible to have a mind map showing the relations as in Storybook. On the other hand, Scrivener has more text writing stuff, eg. text formats, where Storybook mainly is a plotting tool (at least for now).
