Add a "last logged in" field to profile.

Hi, when you hover over members avatars in easy social you can see in the pop up when the user was last logged in, this is really useful as we have tons of members and you can see quickly if they have been recently active.

However when you visit their profile, there is no way of knowing when this user was last active unless you study their timeline which is not always a direct indication.

Is there an easy way to add "member last logged in" to their profile fields or on the front page of the profile itself? Jomsocial used to offer this functionality and it was very useful.

Many thanks.
