The Name field in both the listing of contacts and list members is helpful, but it is empty for organization contacts (those contacts without a first & last name but which do have a company name value). It would be great if both of these API calls would list FirstName, LastName and CompanyName separately.
Even better would be the ability to specify additional fields to include in these API calls. There are few fields I would like to download for every contact to synch with my local system. It would be great not to have to make a separate API call for every contact to get that information. If including these fields were optional, it wouldn't affect those who want a quick list.
