A couple comments on the new Navigation Update that is partially rolled out as I understand.
With additional use of the far left pane it reinforces the need to have Expand All/Collapse All at the Team level. The new navigation allows you to collapse all Teams to one line that says Teams but this really needs to collapse leaving just the Team Names especially when Teams are often used as departments or many other ways.
I believe when you are a member of multiple companies the company that you were in use to show up under picture on upper right hand corner. This is also important for those who navigate among multiple companies.
Thanks for the continued development
