We have implemented a significantly different and improved design. The page now has a table layout with sortable columns. Instead of subway map lines, users can see related groups and policies through a tooltip rendered on hover. Actions such as Run Policy, Assign Group/Policy, Remove Group/Policy and Manage Approvals (for manual policies) can now be executed directly from the Group/Policy table instead of having to access the edit page of an individual policy or group.
Watch for this to be released later today:
