Sometimes, when I upload/download a file, it takes too long... So I went off the office, to take a cup of coffee, or something like that.

It would be nice to have an option where I can set an action to do after complete the task. For me would be useful if it can send me an e-mail, alerting me "hey, your transfer of xxx.file.zip is now completed!". Maybe for another user, would be useful have an option to shutdown the pc/mac when it finish all transfers. It isn't so hard to develop, and I think that it could be useful for many of cyberduck's users.
