Heatmap shows resource usage with color tinting:
- Green/Blue — Low usage
- Yellow/Orange — Medium usage
- Red — High usage
The CPU and RAM sparklines show real-time resource usage history (60-sample rolling window). The CPU graph shows total and kernel time; the RAM graph shows memory load percentage. They update at the configured refresh interval.
A dedicated window showing detailed hardware topology, memory metrics (including commit charge and kernel pools), and I/O statistics across four tabs: Summary, CPU, Memory, and I/O History. See System Information for details.
Yes. Go to Settings → General → Theme. Choose from CyberManager, Dark, or Light.
Enable Minimize to tray in Settings → General. The close button sends to system tray.
