We have had instances of team members sharing entire Workspaces in lieu of Sheets to external parties. This poses a risk of non-company personnel viewing aspects of a Workspace that they shouldn't.
We typically grant all company team-members Admin rights due to the limitations of Editors (not being able to create new sheets for instance is very limiting); this opens up the possibility of Sharing Workspaces erroneously.
Security & Controls has a number of Publishing Functions nominated.
I should think that the inclusion of Workspace Publishing/Sharing is a good option for Company Admins to manage.
I completely agree with this. I want my users to be able to share the individual sheets - but they are erroneously sharing the entire workspace. We have clients who have very sensitive data that CANNOT be shared.... if I could set this permission at a group level - that would be IDEAL!
