I don't like the new look because of the side tool bar, I want to switch back to the old look

How do I switch back to the old Adobe look? I don't like the layout of the updated look. I mainly work in a split screen (adobe on half the screen, something else on the other half), and I like to see the entire pdf so I have it fill the screen. I edit pdfs a lot so having the tool bar on the side when I'm working split screen doesn't work for me (it's functioning properly, I just don't like it) because it makes my pdf tiny and hard to see. Could I zoom in to make the document text larger? Yes, but I don't want to be scrolling up and down and left to right, I want all of my information in front of me, and easy to see all at once. I want the old Adobe Pro that I know and love, with the tool bar on top back. Please tell me there is a way! I've been giving it a chance for  or  months now because normally I have no issue rolling with updates.
