  o more nice icons for different fs-types (root&non-root)
  
  o  sorting the devices by the selected (clicked) header
  
  o  floating settings-window instead of non-kdeish wrap-on
  
  o  right-mouse-button menu for mount/umount, openFileMgr
 
  o  don't use a forked df-command but implement all by my own

KNOWN BUGS:
  
  o  if you try to mount an unreachable NFS you will have to
     wait for a long time to get the timeout (and kdf is blocked
     the whole time)
