How to do side-by-side editing of 2 different files in Writer?

want to desert Word 2003

Is there a newer answer than Mar 6 '14? It appears a “right answer” was accepted on 2016-02-20 by Alex Kemp but I see no recent (i.e. 2016) posts.

At present, open two files (separately) and resize the windows to suit the screen area. The related enhancement bug is fdo#31481.

Many thanks. Patience is indicated.
