If anyone hates the new look (completely blank on one side of the screen) and wants the old layout back (the one before this one) just load up youtube and press ctrl+shift+j (or ctrl shift K if you're using firefox) and put in this code in the box

Code:
document.cookie="VISITOR_INFO1_LIVE=qDpUsBNO0FY; expires=Thu, 2 Aug 2020 20:47:11 UTC";
Refresh the page and it should be back to the old style.
