It would be nice if there was an option to delete imported nzb file (I sometimes forget which ones I imported and then I have to manually check every one of them after dl to weed out finished ones), or better still rename imported nzb file, add "imported" in the name of the file or something like that.
It would be best if the program would delete nzbs AFTER a succesful download or succesful par check, but I know that is more complicated and probably unnecessary.
