If you try to shrink your Whatsapp Web window to the side to make space for another window, the chat you're viewing gets obscured by the sidebar. This extensions makes it possible again to get to your chat by automatically hiding the chats sidebar. - If you're not currently viewing any chat, the sidebar stays in view. - To go to another chat, click on the 'Chats' button in the top left to get to the sidebar; it will auto hide again as you click on a chat.
