OK, so now that I have KA/Pi working, I've found a couple bugs/RFE's. First of all, there is a sorting problem with accented charactes that are used in spanish, french, german and other languages. All accented letters should be sorted as if they were the unaccented letter (so á, â, ä, and so on should be sorted the same as "a", ñ the same as n, and so on). Not necessarily a major problem except if a person's first or last name starts with an accented letter, they get sorted at the end of the list.
It would be nice to have an option where, if there is no first/last name, the company/organization name gets displayed/sorted instead. This would be optional.
Aside from that, from a first look, this looks like a wonderful suite! Congrats to Zautrix, Ulf and the rest of the people involved!
