- Print image
- In multiple image mode, allow to save and export only the current image
- Load the contents of the TikZ commands menu from an XML file
  (this would require an XML file for each translation :-( )
- Clicking an item in the TikZ commands dock widget should not insert
  it, but only select it.  Pressing an Insert button would then do the
  actual insertion.  There should also be a Help button which opens the
  TikZ manual at the page where the selected item is explained.
