Wide blank space under Fusion nodes that I can't remove

I have a tall blank space under the 'Nodes' panel of Fusion that I can't get rid of. Right cliking does not help. It's wasting a lot of space. I've attached an image.

So many things are just difficult to figure out on your own. But with time, I'll start to get up to speed. So now I know about the "clips" section and using the 'middle mouse' with it. Now just 100,000 other things to learn and I'll be an expert...lol... Thanks again.
