Gmail Labs rocks. There are lots of cool features in there that I’ve enabled and I love the whole concept of how they happen.
To any Googlers looking for something to spend their 20% time on, here’s an idea:
I’d like to see an option added to the drop down menu for an email (or done some other way!) to create a distribution list from the email addresses in the To/Cc lines. Automatically add those people to my contact list if they don’t exist and then take me to a page to name the group.
I often find myself looking for this feature and Gmail Labs is a great way to get it.
