Change whether new articles appear at the top or bottom of a section

In the current behaviour, if you set the order of articles in a section to be manual, then any new article you create appears at the top of the articles in the section.

This is very annoying. The first article in a section is usually created early and set in stone -- often titled something like "Get started with ..."

I can't think of a time ever when I've created a new article and wanted it to come at the top.

It's particularly annoying because non-admins can't change the order of articles. So every time they create a new article they corrupt the order of their content. 

I would like to be able to select the default behaviour: whether an article should appear at the top or the bottom.
