  32  * TODO: The current implementation is a temporary
  33  * workaround for the 4.9 release and represents no
  34  * real facets-implementation yet: There have been
  35  * some Dolphin specific user-interface and interaction
  36  * issues since 4.6 by embedding the Nepomuk facet-widget
  37  * into a QDockWidget (this is unrelated to the
  38  * Nepomuk facet-widget itself). Now in combination
  39  * with the search-shortcuts in the Places Panel some
  40  * existing issues turned into real showstoppers.
  41  *
  42  * So the longterm plan is to use the Nepomuk facets
  43  * again as soon as possible.
