I think it would be a good idea to allow the rendering of emails in a stacked layout to render in reverse order.
Now I always have to scroll to read the mail and I see a bunch of

Example;

If I have a conversation with let's say 16 Emails. I open that conversation 60% of the view is just the collapsed headline of our emails. And I have to scroll to read the entire new email. This is even worse on mobile that some emails I do not even see before I scroll.

To me this is not logic at all and I would like for it to work like gmail does it, always show the latest unread message at the top and let me scroll if I want to read the older emails.
