It would be useful show the user that is logged in on the menu bar. When you have more than one user and each has their own login there is nothing to show who is logged in on a specific machine. If sharing a machine it means that users can be operating as each other by mistake. While logging out after use is the best option this does not always happen and you have no idea who is logged in unless you log out and log in again. Showing the username, or icon as on the community page, adjacent to the company name on the right of the menu bar would be great.
A further enhancement would be to have a “Switch User” option in the dropdown.
