Politics vs. UI

I'm working with Express.js and have been visiting their docs a lot over the past few weeks.

I work on my 13" Macbook so I don't have much screen space.

My screen looks like this: https://i.gyazo.com/1af48ab36b4c69c21c96d52d6267b6bb.png

I gotta say I'm not too happy with the banner up top, which is blocking about 15% of my screen. I feel like it's getting in the way of good UI. I can't close it. I have to go into the source code and put a hidden tag in the HTML, but most of the time I'm too lazy to do that, especially when I'm checking something quick.
