The Outlook contact forms are poorly designed.  Why not have a tab for
personal information, a tab for family information, a tab for employment
information, a tab for hobbies and interests?  Then let the GENERAL tab
simply summarize key elements of the other tabs as an overview.  This would
be so much more intuitive because it helps users organize contact information
into logical areas of interest.  For example, the current contact form mixes
business and personal information on the DETAILS tab for a contact and
doesn’t even have a way to list a person’s children for reference.  Children,
for example, are not only helpful for personal use, but professionals, like
doctors and dentists, use this reference information for cultivating
meaningful public relations with clients.  We also like the approach of
different forms for different types of contacts.  For example, WordPerfect
used to provide different types of forms depending on whether the contact was
a person, organization, relationship, or other type of contact or link.  It
was very logical and had customizable fields tailored on the form for each
type of contact or relationship.  Outlook 2007 also seems to have hidden the
ability to link contacts together.  Again using WordPerfect as an
illustration, there was a many-to-many linking feature that allowed the user
to easily link children to parents, parents to children, people to
businesses, etcetera.  Even information such as birth dates, death dates, and
christening dates, with the ability to link families together, would be
useful to genealogists maintaining family directories.  Not to mention that  
genealogy is allegedly renowned as one of the largest volume uses on the
internet.  Finally, as always, the user should have the option of customizing
all aspects of the forms and tabs, but better default form design might
minimize the need for customization.
