      pros, cons and recent comments
      This is a quick alternative to visually compare text files. When the diff is complicated (moves, three way, etc) it falls a bit short.

      Allows to do quick comparison of files or some copied parts of the files. You can use all other powerful features of Notepad++ and plugins while comparison, such as sorting the lines, removing duplicates, highlighting some words, edit and then redo comparison of results right away.
