How to drag & drop headings in navigator window

I remember that when I used Writer for the first few times, I was able to drag and drop headings in the navigator window and liked this feature. Now I can’t do it anymore and don’t find help in the help file.

What settings need to be made to enable drag and drop of headings in the navigator window of Writer?

Thanks in advance!

I think you can’t - use the up and down, promote/demote buttons in the top right. There are a whole slew of pretty important bug requests related to the Navigator in the bug tracker, so maybe add a request to one of the existing threads and maybe it will get fixed one day.

@HansHenderson: Thanks for clarification. I filed and enhancement request going a bit beyond above matter.
