"Outline View"

[triari]

This is a feature request.

I want to be able to view all the headers in a document as an "outline view" of large documents, in order to navigate quickly and see the birds-eye view.

So, I'd love the SHIFT-TAB behavior to show all the headers instead of just the top-level ones.

This is what I wanted for a long time. Though it will be better to put the outline in a separate window instead of fold current document into a outline.

Check this package.
