I'm running 1.4.7 on Debian/Buster (AMD64) and just tried to merge two documents by importing the second at the end of the first. Unfortunately this only partially worked as I lost some pretty significant amounts of formatting in the imported section.
It looks like most of the imported text was treated as the default paragraph style even though it is showing the correct styles when I Edit Text. Overrides of the styles (usually where I tighten up the letter spacing a little to fit some long names into a fixed-size box) are usually lost but bold text was preserved. For some reason, some styles seem to be always lost while others aren't. A style I use for telephone numbers seems to have been ignored while one I use for e-mail addresses is obeyed.
