I would like to see a centralized management console for Orion to pull all of the different components together (web or console based are both viable options as far as my opinion is concerned). Right now if feels like all of my different Orion components (Primary Poller, DB, Additional Pollers, Additional Web Server) are all completely independent systems and all have to be managed independently.
Having one centralized console through which I could manage all of these systems (restarting services, load balancing, updating custom properties, etc) would make the management of larger installations much more user friendly and would make the entire product have a much more cohesive and enterprise feel to it.
