(Use the OK button to choose a task selected from the MRU popup list, or the New task button to choose from the Rosetta Code task list page)

(These drop-downs require Yosemite – they use a bit of JavaScript for Applications to prune any duplicates out of the 'up to 12 most recently used' lists:

(function(strLangs, strLeft, strRight) {
  return [strLeft, strRight].concat(
    strLangs.split('|')
  ).reduce(
    function (u, x) {
      return u.indexOf(x) === -1 ? u.concat(x) : u;
    }, [] 
  ).slice(0,12).join('|')
})(
  "$KMVAR_langsVisited",
  "$KMVAR_left_language",
  "$KMVAR_right_language"
)
