very interesting idea / piece of code.
One potential problem that I see is that (point) is a property of a
window. Only if a buffer is shown in one or zero windows, then (point)
is unique after a set-buffer operation for this buffer and you can use
it to select which part not to hide.
So what might happen is that you can have two or more windows on a
buffer (in the same frame, or even on different frames), each looking
at a different section of the outline tree. I often do this when
restructuring a file, while moving stuff from one place in a file to
another. Your code would keep closing some of the visible outlines,
because it only considers (point) in a single window (I don't even know
which one if would actually use in this case, an interesting problem).
To solve this, you would need to check if a buffer is displayed in
several places, make a list of (point) in all these places, and then
check is any of the listed values of point fall in the outline subtree
you are about to close.
Finally, you are running it on an idle timer with 60 seconds of idle
time required. I would be interesting how this works in pratice, and
if this is the best way to activate this code. For now, I have not
tried it extensively and I don't know.
