It is already planned in tickets http://trac2.assembla.com/SABnzbd/ticket/315 . I would like to add the possibility to re-download parts of the job.
Sometimes, some rar files are partially downloaded because of network failure or server failure ..; This results in CRC failure and par files do not always succeed to repair it.
Being able to select the files to re-download would be great. Highlighting the files that caused CRC failures is even greater
Thank you guys for this great piece of software !
