This tool also has a number of other improvements.Detector response functions, for a number of common detection systems have been added by default.The application now can generate and receive "interspec://" and "raddata://" URIs through QR codes, to help transfer spectrum files or application state, without network communications.Lots of general bug fixes and improvements, as well as improved iOS specific behavior, like opening and exporting spectrum files.
