Compressor Options has an option to specify the thread priority for compression operations. I find that it is not saved between sessions with different datfiles, like all other compression options are. I tried to use 'Save As Def.' in the Settings dialog box, but that didn't work either. It is unavailable to select while batch loading, so I do not know a workaround other than manually specifying it for each of the 770 dats (400,000+ files) I need to scan with. Would this be considered a valid bug to fix?
