Google rolls out a new "Gmail Contacts," that now works more like the rest of Gmail, with a bunch of new features including: "Keyboard shortcuts (go to Contacts and hit "?" for full list), Sort by last name (look under "More actions"), Custom labels for phone numbers and other fields, ability to undo changes you've just made, Automatic saving, Structured name fields, so you can adjust titles, suffixes, and other name components, and a bigger, more prominent notes field".
Also improved the layout to easily get to "Contacts and Tasks" which're now located at the top left corner along with a link for "Mail" that takes you back to your inbox. If you're not interested in Contacts or Tasks, you can hide these links by clicking near the right edge of "Mail." Overall, there's now a smaller header area that puts the first message in your inbox about 16 pixels higher on the screen than before.
Google Apps will get these features later.
