Let me first tell you my specific problem:
I'm setting up mail.app for a senior citizen (read as in bad eyesight, bad hand-eye coordination). I taught a setup were emails would be sorted by newest first. But every other week it happens instead of opening the most recent email some sort column would be clicked (and emails will permanently be sorted in some non-intuitive way). Reproducing the order is a "precision" task the person can not do alone.
So I'm asking is there a hidden option to permanently disable this feature (similar to iOS)? Or at least what would it take to program some tool that will revert this "setting"?
