Now Deluge is very usefull, thank you for your work! But there is some small thigs that could be better. First, if you delete or move from system file manager already downloaded file which is in active torrent, deluge will download this file again without any prompt. If you have a lot of active torrents it's very difficult to look into deluge and look for a file before deleting it. It will be very usefull if there is an option in settings, which turn on a prompt before re-downloading already downloaded files.
Second, when the flashing icon option and autominimize window option are enabled and deluge is autostart process, each time when you boot on you computer deluge icon start flashing even if there is no uncompleted torrents in list. This is a bit annoying

I'm using Ubuntu 9.04.
