To make fair since the twitter is limiting also for ratio between following and follower then it is beet to add a button " Who I followed who did not follow me back"
Many twitter user used to follow somebody to be followed back then later they will unfollow because of their EGO that they would be proud that many follower than they followed.
We should make this fair…
We could see who are we followed but we could not see if they followed us back or not
