In HELP Center Document pages, left pane is totally useless , please drop that part from the page.

In docs.oracle.com (Oracle Help Center) reading documents, include but not limited to:

On the left part of the screen is really annoying.

Not alone taking 25% of my screen space. but also provide no helpful meaning. Plus three more caveats:

1. Search bar return nothing at all.

2. Feedback button servers no function.

3. Download button is totally useless.
