When LibreOffice is run as an appimage, it would be good to have a Help menu entry to update the running appimage. The appimage developer has suggested the following code logic. "if environment variable $APPIMAGE exists and if AppImageUpdate is on the $PATH, then show a button that, when clicked, calls 'AppImageUpdate $APPIMAGE'"
AppImage is not current, last daily is from January. So this is WontFix IMO.
