'Layout manager' window behaviour

Is it really necessary to keep ‘Layout manager’ window always on top even when Scrivener is not foreground application?

In order to allow the layout manager to remain on top of Scrivener windows, yes, it’s necessary for it to remain on top for everything. You can add the Layout Manager icon to the main toolbar to toggle it on and off quickly.

Thank you!
