Home screen Layout w/ history

[Shellikinj]

I always view my tablet horizontally (landscape) rather than vertically (portrait). When I open the app, the Home Screen takes up 2/3 of the screen and the remaining 1/3 is the History. How do I remove this portion? Unfortunately, there is no X to close it and no option in settings to hide it. Nor can I find a way to make the Home page full-screen. I hope this makes sense. Please Iet me know If any clarification is needed. And I sincerely appreciate any help offered. Thank you and have a Merry Christmas!
