I think it entirely reasonable not to offer Save from preview mode.
(I am the reporter of bug 48348, and I only realized that preview mode
was involved when I came back to my saved file with a fresh build and
then *accidentally* came out of preview mode.  That just about proves
that I did not need to save from preview mode, doesn't it? <grin />)

There remains a question about what the program should do when the
user (or system?) closes the application while a changed document is
in preview mode.  I think the Save/Discard dialog at this point is
still highly desirable.  If it is easiest to go back to the editing
program and let the editing program handle it, I think that would be
fine.

I think that the option to close a single unchanged document from
preview mode sounds useful but not essential.

All this, of course, comes from my way of working with LO.  YMMV.

HTH,
Terry.
