Signing into Multiple Google Accounts on the Same Browser

So I know I am late to do this, but for the few of you who also haven't figured it out, if you click on your name when you are in Google Drive, a new browser will appear and you simply add the "Add account" and a new tab will open up where you can then sign in and toggle between the two tabs.  Of course if you want them side by side you could just grab one of the tabs and pull it away thereby opening a new browser and then you could show them side by side.
