@Suty that's really good news!
I just discovered the app and bought the premium subscription based on the sheer amount of data available, but when I realized the humidex was missing, I was about to ask for a refund. Then I saw this thread.
In my mind, temperature without humidex is close to worthless. Gearing up for 26°C (raw temp) versus 37°C (humidex) is a world of difference.
Please push this one through, count me as another vote! Hope the internal testing phase goes quickly.
