  • Shows the differences line by line and character by character.
  • Automatic merge-facility.
  • Integrated editor for comfortable solving of merge-conflicts.

  • Supports KIO on KDE (allows accessing ftp, sftp, fish, smb etc).
  • Printing of differences.
  • Manual alignment of lines.
  • Automatic merging of version control history.
