  ft-float float [ID|active]   float a window (default: the active one; for it, a toggle)
  ft-float float pointer       the float key: float the window under the pointer (else the

  ft-float dock [ID|active]    put a floating window back on the desktop
  ft-float dock all            put every floating window back
  ft-float launch APP          start an app (its desktop file name, e.g. org.kde.dolphin) and
                               float its first window where that app last floated
  ft-float run COMMAND [ARG...]  the same for a command
  ft-float close ID            close a window
  ft-float list                the spare outputs and what floats on them
