Forgive me if someone asked before, I could not find it in the issue list.
Beside node create/edit restrictions, is it possible to restrict vieweing access to the nodes assigned to the sections? Like it was with Organic Groups, you could type a piece of content as private (viewable for section members) or public (viewable for everybody).
If not, do you hevae a suggestion that adds to Workbench Access as it is a very nice way to group content.
