I would love to see a mode where I could get the metrics in or beside the system tray. I currently have a program called TrafficMonitor that gives this for CPU and memory

To me, either in the System Tray or (like TrafficMonitor) next to the System Tray would be nice.
Having the ability to choose what to display would be nice. Stacking like TrafficMonitor would save space. Choosing colours and fonts a really nice bonus.
AppControl is already a fantastic program. This would make it even better!
