We use an external login provider and do not use the email address as the username. In previous versions I could create a new user with a different username than the email address. However, as of 7.7 the interface to create a new user only allows you to enter an email address. Then, when editing the user details after that the username is not displayed because it is set to the same value as the email address. I then have to manually edit the record in the "umbracoUser" table to change the username. After that, I can then edit it in the interface. I need to have an option to always show the username, regardless of whether or not it is the same as the email address, so I can edit these like I did in previous versions.
