Oh, thanks for your answer!

So do you know how I should edit the widget to make it take into account 0.1 grades instead of grades? Currently I think the widget is still made for grades, so when it detects a temperature ranging between 200 and 300 units, it must say "Whoo hoo mate, your phone is burning; you wan't me to overclock the CPU? No way!"

I'm speaking about the "Temperature" button of the widget.
