I'd like to see some functionality similar to how "The Dude" does their network maps.  Specifically, if a node has a service down, you have the ability to have the service that's down show up beneath the affected node (or next to).  The tooltip has similar functionality if you have the DCIs set to show on the tooltip, however there's no way to show that without interaction.  Ideally I'm looking for this to be a dashboard on a front of the room TV that someone can glance at and say hey, the X service is down.
