Along the right side of the screen, right below your Google account avatar, there’s a new sidebar that gives you quick shortcuts to Gmail companion apps. It’s one of the most obvious new features when you open the new Gmail for the first time. Now, Google’s letting you hide that pesky new Gmail sidebar that you never use. We’ve been fans of it for quite a while from purely an aesthetic perspective, but it’s definitely had some places where it feels like Google chose form over function. Google launched a completely redesigned Gmail on the web, featuring the Google Material Theme, earlier this year.
