With TCA, I can no longer input the desired altitude to hover using the keyboard. My keyboard has a numeric keypad. Input using both the keypad and the keyboard doesn't work. The -10/+10 buttons work, so I have a workaround, even if it takes a fair bit of clicks to get to something like 360 meters altitude.
