I was trying to download a folder via sftp with a few hundred thousand files in it, but something went really wrong. And, as a suprise Cyberduck thought that it was a good idea to make a growl popup for EVERY file downloaded.
I smart grouping of growl notifications would be nice, so cyberducks only say something one time, and not fivehundredfiftythousandtwo or something like that. :)
While the fix is easy, stop growl and start it again that solution may not be thought of by a newbie user.
