One thing I really wish for is a separation of phone numbers from contacts. Currently I kind of get around this by making a group for friends phone #s, then one for business XXX, then another for business YYY, etc. I'd really like to have phone #s in its own separate tab and have something on that tab that I can expand to slide out the dial pad.
A separate tab would reduce the group name pollution that I currently have (since I now must have two categories for each .. i.e., "Business XXX IM contacts" plus "Business XXX phone numbers"). To me IM and phone are two very separate functions and I would like to see them treated as such.
As a s/w person my thinking would be to generalize this to a three level system visible as tabs, groups, and entries. Then *I* could create a tab called "Phone #s" or "Business XXX", or "Contacts with Video" and put my groups (containing entries) in whatever form I like.
OTOH as a s/w person I also recognize how complex it is to make something simple.
