Currently you have the option: "Minimum free space for Temporary Download Folder" where you can let SABnzbd pause when the temp disk reaches the limit. Also in the Plush queue there are two free space indicators. One for the disk containing the temporary download folder and one for the completed download folder.
When the temp disk has less free space than the total amount in the queue the text gets Red. This is unnecessary since the individual items in the queue are (way) less than the amount of free space. So the temp disk would not get full as the data is extracted to the completed downloads folder on another disk. (Assuming you use +Delete.)
I'd like to see it work like this:
"Minimum free space for Temporary Download Folder" should be "Minimum free disk space" (used for both disks). SAB should sheck both disks and pause when either is at the limit. When the total queue size exceeds the free space on the completed disk the corresponding indicator in the queue should turn red. When any individual queue item exceeds the free space on the temporary disk the corresponding indicator in the queue should turn red. These should be the only conditions when the indicators turn red.
Keep up the good work! Love the program.
