Reader DC Menu Items are too big!

Hello!

It may just be me and my personal preferences, but the menu items at the top of the Adobe Acrobat Reader DC (the "Home, Tools, page viewer" and the line below with the button options), together with the typical heading and menu items are just too big. They take up 1/4 of my screen and leave less room than I would prefer to actually view my document! Is there a way to change this manually? I'd love to get rid of all of that wasted space so I can be more productive!!

If not, please consider this suggestion. Compared to Microsoft Word, the icons are way too big and seriously waste space sitting up there.

Thank you for your consideration, Laura
