Gmail's contact groups have received a couple of minor enhancements today, to make the overall experience more user-friendly.
First off, you can add multiple members to a group at once, by just copying a list of email addresses and pasting it into the Add to group menu when viewing any particular group you've created.
Second, you can now specify which one of a contact's email addresses to use in a particular group. For example, this now lets you use a friend's personal email address in one group, and his or her work email in another group. This is a very neat feature since an increasing number of people have different email addresses for personal and work purposes (or should, anyway). And now it's easier to manage such people's information in Gmail contacts.Gmail gets improved contact groups
