Though most of Wikipedia articles contain link to Commonscat and the link is either local or included also as P373 in Wikidata, this "feature" ignores both those. Instead of employing all the information from Wikidata and compensating deficiencies of Wikidata, this feature does almost nothing useful.
Also the position of the link within the sidebar is not just bright. Why it is added to general tools instead to interproject links? Why the interproject link to Wikidata is in different section than inteproject links to Commons or Wikiquote?
Why were not applied and employed experiences from similar tools which were and are used on some local wikis and are better designed and more perfect?
