Make your Gmail easy to access without adding a new tab to a crowded window with this extension. This simple tool allows you to open Gmail in a panel that shows an optimized display of your account. 

It shows a simplified version, but you can still access all the folders, such as your inbox, sent mails, and starred mails. You can also search for emails and switch accounts. It is super easy to use. All you have to do is install the extension of your browser, enable the panel flags in Chrome, and sign in to your account.
