In NX2, roles were managed in a tree view. This allowed an admin to select a role, and if it inherited other roles, see the actual permissions granted by those roles.
In NX3, there is no tree view. You can see directly granted permissions, and inherited roles, but there is no way to see what permissions are contained in those inherited roles without backing out of the current dialog and going to look at the other role manually. This becomes more tedious the more levels of inheritance there are.
There needs to be a way to view the complete contents of a role on one page.
