Clearer Visibility of Email Address Being Used When Sending From Unified Inbox

When composing a new email, it would be useful to have clearer visibility of the email address the email is being sent from. The email being used is visible, however, when composing an email in a hurry, sometimes checking the email address being used is overlooked, meaning an incorrect email address being used (e.g. sending client email from personal email address instead of business). Not sure what the solution looks like, but something to draw attention to the email address being used.
