Why not add an option in "File - Preferences - Language", such as "Display Native Language Names"? Maybe it is the best solution till now.

Are you serious? If you want to change SensorPanel temperature unit from Fahrenheit into Celsius, first you have to go to "File - Preferences - Hardware Monitoring" and select "Display temperatures in Fahrenheit", and then show the SensorPanel and... If you want to change SensorPanel temperature unit back into Fahrenheit, you have to do the opposite with so many clicks. Do you think that is a good idea? Another four problems: 1. "File - Preferences - Language": Why do you add native language names after its English language names? Those native language names can not be displayed just as they should be on any operating system of any language included in the language folder. It is annoying. The suggestion is: If there is no perfect solution, delete them. 2. How to display temperature symbol perfectly on any operating system of any language included in the language folder? 3. The default language version is in English, you should add other native language support in it. 4. If there is no perfect solution for the SensorPanel, delete it, or provide another version of AIDA64 without it.

I have tried what you said in another way before: Right click on the Panel (not on the Panel item) and seek for a "one-click-for-all" solution. But it seems that does not work. What you mean is that one can only change one item each time? That is not a good idea.

But where "to manually change the displayed unit text for each temperature SensorPanel item"?

Your USB Adapter must be USB 1.0? If this is true, eject your USB Adapter, and everything goes fine.

The default SensorPanel temperature unit set by FinalWire is Celsius. If change it to Fahrenheit, temperature number is Fahrenheit, but the unit is still Celsius.
