@Burunduk :-
Nice work! I can see this working well for those who want to update regularly.
Me, personally, I tend to find a "recent" version that works for me, then stick with it for quite a while. Like I said, I rarely write documents anyway - or 'share'/collaborate with Windows users - so for me, always having the latest, most up-to-date compatibility with M$ Office's ever-changing protocols is NOT a priority.
Well done. You'll have to make this easily-available for the community, so it's not hard to find.
Mike.
