"WINDOWS 8/8.1/10 NOT CURRENTLY SUPPORTED, WORK TO MAKE IT COMPATIBLE IS ONGOING" yeah most likely it won't working on the windows listed in the quote, there is progress on it so it is bound to come out with Windows 10 support <3.

Oh for that last question I wouldnt be too sure, if the demand was higher then ofcourse
