Refollow (interestingly not supported on IE during beta) is a full relationship manage for Twitter. (This site is worthy of a screencast and I will do one and relink it)

You utilize your Twitter account but it authorizes as an application, which is a nice change. The UI is sleek and clean with many options. It begins by loading the avatars of 200 friends and followers of the account you authorized.
At the top you are able to check boxes to only show those you follow, those not following you, locked and unlocked (I weill cover this in a moment) and Name Like to find users in your collection.
You can also filter from the right users that are following someone else. Basically they give you numerous ways to easily follow, unfollow and sort users. It did the default 200, which worked out to be 100 Following and 100 followers. There were options to load more or all of each of these categories.
I filtered to show users that follow Corvida and it quickly brought me 100 of her followers. From there I could filter the list to see who followed me also or even ones I didn’t follow so I could follow them. it goes on and on. Hovering over any avatar gives you stats and information on that user.
Since you are pulling lots of data, your API count shows in the corner and how long till it resets.
