UX: Current MUC nickname should be displayed somewhere
In a MUC, i have to go in the hamburger menu then "Change nickname" just to see my current nickname. It would make sense that it is displayed somewhere in the UI, along with a quick button to change it.
In my view, this would make sense near the current account context in the top bar.
