Thanks for the feedback, Shivam! I don't believe the Contacts layout will be changed in the remaining BETA builds. As such, I'm going to mark this thread as Declined.
That being said, this is definitely a valid request for future versions of SmarterMail. Another request for a list view in Contact was created prior to this one with more votes, so we're going to continue using that thread for tracking this request in the main SmarterMail category. Please be sure to add your support by upvoting the thread, and subscribe for future updates:
