Here's an idea to take SmarterMail to the next level -- sync SmarterMail contacts with the address book from a user's LinkedIn, Facebook, or Gmail account.
Almost everyone has either a Facebook, LinkedIn, or Google account. Why should I have to upload pics and enter phone numbers, job titles, etc. for all my contacts in SmarterMail when this info already exists in these other systems. Plus, the info is updated by the addressee.
Doing dynamic updates with cloud-based address books would be a nice enhancement and put SmarterMail ahead of the competition.
