I have (in retirement) been putting together a novel (Sci-FI Arrival theme). I have now some 300k words in several 'chapters' using Libreoffice writer. I don't find it easy to merge chapters as I did not start with a template. Should I move to a different text editor and if so which one? I just want to tidy it up but unlikely to publish formally; hobby really but would like to be able to break it up and let some family who like such to read it. Many thanks.
