Currently we can only view permissions from group/user perspective, i.e. we can select a group and see the list of authorizations. It would be great to be able to ask QuickBuild: "which users and groups have permissions to this or that configuration". This perspective would give administrators better control of permissions. With more than 1000 configurations and 600 users it's hard to make sure that there are no obsolete authorizations left for configuration X or Y.
Ideally, UI should have a search box or a button to query QuickBuild, but REST API method would also be sufficient.
