Google is in the process of rolling out its enhanced version of Gmail's contact manager, which will feature automatic saving, standard keyboard shortcuts, an undo button, a way to sort contacts by last name and a way to make custom fields if the ones provided are not what you need. Google has also moved its contacts and task tools to the very top left part of the page to make them more prominent.
If you have not yet seen these changes in your Gmail, they are on their way. If you have already received them and tried them out, let's hear your thoughts and tips if you have any to share.
