How to save only one page from odt document (which have several pages) as new odt document ?
LibreOffice Writer 4.3.2.2
To the best of my knowledge this is not possible (test made again with Writer LibO 4.2.7.2).
However this could be an enhancement request as it saves a lot of time with workarounds. I have to do the workaround maybe 3- 8 times a year.
May I propose you file an enhancement request here: https://www.libreoffice.org/get-help/bug/?enhancement=yes
