Achieves what others can't, but limited

It’s the only simple way to automatically display the output of your custom fields, without touching any code or creating new templates.

That’s the good bit. Unfortunately, the fields output as an unordered list and that list is above the post content. There is no option for changing the position of the output, although it has been requested.

You can of course style that (bullited) list. If you simply want to show your custom fields nice quick and easy, this is the only non-code option. Because of that, it gets full marks from me. A little more development and it would be a clear leader.
