The system tray icon was originally the main part of Katimon. It's purpose is to provide a quick overview and an entry-point to the rest of the application.
The icon has three bars. From left to right:
The first one shows the current fan speed. This is shown as a percentage of full fan speed.
The second shows the gpu usage. Again, as a percentage.
The third shows the current temperature. This is scaled to the temperature limits, as they are defined in the configuration dialog.
