In patron accounts, there is always a brief info area at the top left containing the most important patron data (like name, address, category... etc.) It would be nice to be able to configure which patron fields are used for this brief info area. At the moment it is only possible using system preference HidePersonalPatronDetailOnCirculation to hide all personal fields from the brief info area. But some libraries might want to add more info to the area, or remove only some select fields.
