Ok, so if I understand correctly, with foldmethod=marker and the default fold
markers, and this example text:

folded text {{{1
is great {{{2 {{{3
for showing only parts }}}3
of a file }}}2
or maybe an outline }}}1

With all folds closed, this turns into:

folded text

After pressing zo:

folded text {{{1
is great
or maybe an outline }}}1

Now press zo on the "is great" line:

folded text {{{1
is great
of a file }}}2
or maybe an outline }}}1

But instead you want all folds open.

This cannot be accomplished with a simple option setting. However, if you press
zO or zA instead of zo or za, then any folds under the cursor will be opened
automatically to any level. Maybe this gets you where you want?

The other possibility I can think of, is to start with all folds open, then use
a :g or :folddoopen command combined with foldlevel() to close folds selectively
using the :foldclose command. This could be done in a BufWinEnter autocmd, for
example.
