I couldn’t find a suggestion forum, so I figured this could work. I think it would be kind of cool if the little shadow bird/water print bird on top of your twitter screen could turn blue or lay an egg or something when you got a personal mention/reply. This is more helpful for the newer users or the users with a smaller follower ratio vs their following ratio. I know there is a @discover or mentioned section, but it is just another helpful hint if the user isn’t well versed in twitter. This would really be no bother to those with larger follower bases, simply cause the shadow bird would typically always be blue due to the abundance of people following them.
