I've had a number of occasions where I've left the bot running, but when I came back to check on the progress, the computer had gone into sleep mode. I know I can turn off that setting on the computer, but it's a useful feature to save on energy. I've looked for this option in PF, but I don't see it there, so I think this could be added as a helpful feature so those of us who want the PC to sleep when it's not being used, but don't want it to do that when PF is running. There are already some other programs that have that option (like torrent clients as one example) so it would be great if PF included that option as well.
