14.11 Does KDE have a graphical FTP client?

Yes, and it's none other than your favourite filemanager, KFM. You can drag and drop remote files into local directories. There's also a utility called KGet that allows resuming and queueing, but you need to use it in combination with KFM (you can drag-n-drop into KGet but cannot use it to browse FTP servers).

Of course, you aren't required to use FTP clients provided by KDE at all. WxFTP seems to be a very popular alternative.
