What does not
One thing I notice missing is: in Windows if you download a file from Uploaded.net or similar filesharing (only certain site though) FDM will automatically name your download with the string that appears in the Comment box at the Add Download window, but in Kubuntu 12.10 I don't see any comment in the Comment box, thus the file name is like series of hexadecimal numbers (as seen on my screenshot).
