If you have any suggestions/issues/feature requests, just open a new issue :)! I'm happy to implement more, if it can help you!

simpler on most machines::

  $ sudo apt-get install dictd dict dict-gcide dict-de-en dict-stardic dict-wn dict-xdict dict-moby-thesaurus dict-freedict-deu-eng dict-freedict-eng-deu
  # or even more dict-freedict* stuff
  $ dict approved
