Same question here, and would also like to mention that there have been other, recent, detrimental changes to the web version in my opinion, such as the moving of the 'flag, pin, delete' buttons on hover-over of e-mails in the inbox all the way to the right side.
These kind of changes would be fine if they were OPTIONAL, but as of the past month or two the product feels like it is rapidly getting worse and less intuitive to use. Why??
It was fine, we liked it the way it was. Please at least make it so that the options menu allows for customization in order to keep the lay-out the same as before.
Adding back flag, pin, and delete *are* optional. Hit the three dot menu next to that row, and select customize, and you can add them back.
