Group view for your friends is enabled by default for MSN, Yahoo! and AIM messengers. You can expand or collapse each group or you can disable group view by select “Show groups” in the pop up menu of “View” button.
Group views will help you better managing your friends, especially if you have lots of friends, e.g. thousands of friends for some users.
