I currently use LibreOffice Writer (188.8.131.52) and each time I export a document its default file extension is
.EPUB. Thus, each time when I want the file to be exported as a PDF, I need to manually change the extension from
.EPUB to an actual PDF.
How could I prevent that behavior by locking LO Writer somehow to automatically set file extension for the exported document as PDF?
Note: To export a document I do File > Export > Save (I then change the extension from .EPUB to PDF). I note this after someone asked about it in the comments.
