Adding option for follow back for already followed user

Components

I would love to make a suggestion on steemit.com follower display, i.e the way the follow and unfollow is displayed.

Proposal

User A is following user B but user B is not following user A. When user B goes on user A's page, user B would not be aware user A is following him/her. So, i am suggesting there should be a form of follow back option on user A's page whenever user B goes on user A's page.

Mockups/examples

For example, above is a user i am following, I log onto there page and am not even aware he/she are following me. It just displays follow.

Above, there is a follow back option which allows me to be aware that this user is following me and I could follow back if need be.

Benefits

• If this is implemented, it would make users to me aware of a follower when they go on there page, without going to check their followers list.
• it would help users know people who unfollowed, because it will not show follow back when a former follower has unfollwed.
