I think people can make their own PDFs from many ODTs they have. But if there is no a module (or an application like that) that can accept multiple input of ODF then can convert them one by one to PDF in a same number, people will export them manually one by one. That is a boring job to be done.
I think people will be happy if this module included as a bundle on LibreOffice such as LibreOffice with Writer, Calc, and Impress. So, people will have Writer, Calc, Impress, and this modul (just call it “Exporter”) if they install LibreOffice. That is my idea.
