This extension fixes the jump that occurs in the New YouTube design when you hover over the left sidebar.
If you've opted in or have been updated to the new YouTube design, you may have noticed that hovering your mouse over the left sidebar causes all the content to jump to the right. The reason for this jump is so that scrolling the sidebar doesn't cause the main content to scroll. With 4 lines of CSS, I was able to fix this issue so that the jump doesn't occur while keeping the sidebar working as intended. Want to opt-in to the New YouTube design so that you can enjoy having my extension installed? Head over to https://www.youtube.com/new and click on the big "TRY IT NOW" button!
