Instead of just a "Background" button in the "Copying..." dialog, it would be nice if there were "BG Immediate" and "BG Defered" buttons, allowing the user to have several large jobs that execute in sequence (Defered), OR in parallel (Immediate).
Allowing the user to enjoy a cup of coffee without killing the hard disk.
