"Minimum Free Space for Completed Download Folder:" would be much more useful. After all the temp folder is freed again after something finished unpacking. The completed download folder on the other hand may well reside on another partition or drive and may not be freed so quickly, depending on when its full or when the user has time to clean it up. So if anything should be monitored for free space, it's the drive where the completed files go to.
Should you implement the above, please also provide another option that lets sabnzbd download files to the temp folder until it reaches its free space threshold. Just let it download and forfeit unpacking until there's enough free space on the partition containing the competed download folder.
