The new OpenAccess in v5 is great !
Would it be possible to to have open access views by Teams?
Example an OpenAccess view for Top Management with couple Dashboards and Navigation Menu
Another for Business Users (not seing the same Navigation Menu)
That seems like something you might be able to get raised as a feature request. SquaredUp tends to create formal feature requests if you send them to their support team, so it might be worth doing that and seeing what they come back with.
