Several features that would make user searches and edits more efficient.
1. activate search by email address.
2. if a user search locates several records of people with the same name can Drupal first present a screen with only a few fields about each record instead of the complete list of fields. Maybe name, userid, email address, group lists.
3. once the save button has been clicked on the 'account' screen, can the refreshed screen return to the 'account' screen, not the long list if fields. After making changes to the 'account' screen I always go to the 'admin info' or 'personal info' screen to make additional changes or verifications.
4. move the location of the 'edit' link further away from the 'delete' link.
