AgentViewer shows all unowned agents on the agent roster (with 50% opacity).
It also adds two commands /option AgentViewer_HideOleg true/false and /option AgentViewer_HideBoone true/false which you can use to hide Oleg and/or extra faction agents from the roster.
You can also click on the agents to view their infosheet + drop location (based on This spreadhseet).
