Option: Display Logged-In Account on Browser Extension

Add an option to display somewhere in the browser extension the currently logged in email address, either in full or only the ‘local-part’.
I don’t mind having to log in and out to use multiple accounts, though having to log out just to find out which one I’m using is just plain annoying.
The use case is having a general-use account in a workplace and also some role specific accounts which staff need to switch between.
