"LibreOffice, the free office productivity suite, can be
enhanced with hundreds of extensions and templates. Users can
download these smart extras to improve the suite's functionality to
fit their job or hobby, and developers can easily write their own
add-ons and share it with millions of users worldwide.
Since, at the moment, there is no reliable and stable source for
downloading these handy add-ons, the LibreOffice community has put
great efforts into launching a public repository.
