Creating the titlebar for the recorder popup:

* In the titlebar:
  * Blinkig red dot.
  * A button for closing it and going to the saving step.
  * A list of the recorder steps. You can remove any step you want,
    expect the very firts step with the open command, which is not
    shown in this list.
