Document Outline in VS

Is Document Outline supposed to be empty?

I use DO to navigate inside current file, and to get glance of whats in the file in other languages, and for Oxygene it remains empty.
The jump bar on top is populated with current file metadata - so why not Document Outline? I personally hate jump bar, because it requires clicking and rolling to see anything or get anywhere.

Certainly something like Spade from CodeMaid (C# free plugin) would be very useful.
