View the operator's name in the top corner in new UI
in the old UI, the operator's name is visible in the top right corner. This enables employees at a busy, standing service desk to see who is logged in where and avoid using each others' accounts. In the new UI, it's visible only from the home page.

If you hover your cursor over the "head and shoulders" icon, it shows the user's name, but it would be good for it to be immediately visible.
