>> "I was hoping Adobe Air also getting the same place as other languages, despite it being a little different."
Anything we do for the other languages requires about 40x the amount of work to do the same in Adobe AIR. It's a really poorly designed language, unfortunately.
We do support it and we will bring it up to par with the other languages we support.
>> "Can we get more than one license field at once with GetFeatureValue or some other functions ?"
Nope, you can only read single values at a time. But the algorithm we use is very fast (so getting the values when you need them is as fast or faster than getting all the values and then reading from *that* list).
