    Very helpful Add-In. Unfortunately under LO 7.3 no Icon will be created in the menu-line (maybe changed Install-Procedure?).

    Worked out of the box - great tool with very good results. Under LO 7.0 Windows no Problems. Under LO 7.0 Linux invisible (no icon, no menu-entry - just undiscoverable)

      You have to install for java based extensions, a JRE for LibreOffice.
      Try before installing:
      sudo apt-get install libreoffice-java-common

    I was trying to install your extension on open office writer under windows 8. But I get the following error message (install failure): and install "Could not create Java implementation loader"

      It worked fine on LibreOffice I don't think OpenOffice is supported at all.
