I'm in classic mode. Yeah, in my case there are 'Do nothing', 'Shutdown', 'Hibernate', and 'Suspend', nothing else.
I did try to add it again - didn't help.

hmmm, still nothing. Not sure if i'm using thin client though, how do i check that?
Let's see, i download latest version from here(2.7py, which matches deluge version), and install it as wiki says.
Can i delete plugin and try to add it anew?
Should i have anything python-related installed?

Strange, plugin is v1.5.0 - but no 'once' option.
Deluge is v1.3.15

Hello, i'll be brief:
Please add "Shutdown Once" option, so users won't have to manually disable it every time after a big overnight download.
I sometimes forget to do so

Oh, thanks

Hello, I have a small suggestion on a function to implement.
Same function exists in other major torrent clients.
Basically it will hibernate/switch off your PC after finishing downloads.
