Noticed the makeover of your inbox page when you logged in today? 
We’ve enhanced the overall visual appearance, and usability across the three sections of the inbox page - the conversation listing pane (left), the conversations pane (middle), and the apps pane (right) so you and your team can quickly focus on the right details.
Thank you to all those who took the time to play around with the prototype to share your suggestions and feedback. We hear you and will keep the improvements coming.
