I'd love to have the "<DEVICE> Activites" tab log a timestamp each time a device is noticed ON/OFFLINE. This tab shows some information for Wattbox and other native devices, but IF it could display times it noticed non-native devices (ie - Crestron) have gone ON/OFFLINE it would be extremely helpful at diagnosing problems or identifying what has happened in a system that is having an issue.

I know this would not be a smoking gun for a troubled system, but gives another data point that can be used to determine what may have happened in a system or a component that is going bad.
