It feels a little like going back in time, but having #StarDict installed and the #Webster1913 popping up little windows with beautiful "definitions" (they are way too useful and lovely to think of as definitions) whenever I highlight something is the best clunkiness I've ever inflicted on a computer. Five stars, drawn in crayon!
