In response to referee's comment
"I am also afraid that the ‘snapshot’ and the ‘Export cell data’ functions do not seem to work very well in my hands, could the program be changed so that the correct file extension (.jpg, .tif, .txt, .dat, .xls, .csv…) is given automatically."
I corrected the "exportCellData()" function in canvas.cpp. It did not actually call exportCellData(filename) after the user entered a filename (logic after calling QMessageBox was incorrect).
