It would be useful to list the name of a failing book in the error message of the job log ecpeccially when copying multiple books that might take several hours before it breaks.

KoboTouchExtended (KoboTouch)

How useful could this be

The copy job may break without further notice you loose all that work for nothing and you don't even know what book that caused the error.
