With the new enrolment page (users), if two or more users have the same name, the same profile picture (ie.: the default one) and are listed by the autocomplete field, it's hard to know who is who.
Some information should be displayed to differentiate users that have the same first name, last name and profile picture.
The actual workaround I have found is to inspect the HTML element to note the ID and compared them to the users in the list of all users of the Moodle instance. That way, I can check the user's email address and the list of courses they are enrolled into.
This issue is more important considering we often have people with the same name and/or multiple accounts (the same person can have an employee account and a student account) and that the workaround is not suitable for the management staff, since going in the source code of the page shouldn't be necessary to enroll someone safely.
