When you add a user to Permissions in a repository, the username text field will do an auto-completion of the user name and display name. For example, I can start typing "Valerie" and it will suggest "E12345 (Valerie Wagner)". However, we do not have this behavior in the Notifications plugin. (I'm unclear if the "Name" in this plugin is supposed to refer to a user or just an email address anyway.) At any rate, we would like to have this same kind of capability because our LDAP usernames aren't particularly human-readable ('E' followed by 5 digits) and we don't want our admins to have to go and look up everybody's email address when the SCM Manager already knows the user's name and email.
