Currently no photo can be placed on the shape for organigram creation. That would be from my point of view a good gimmick to improve the look. At the moment you could import photos into the documentation, but this would be visible only after clicking on the element.
If a user has received a license, it is not possible after the e-mail address change. Mostly first and last name in e-mail addresses are used. In a change of name or incorrect entry of all users must be deleted and recreated, rather than simply change the names and e-mail address. This is particularly inconvenient when integrating this person (name) in the workflow. The person has to be re-integrated everywhere.
