Refollow tool

At this time we do not have a demo to show but I can walk you through the process.  

1) Login and authorize Refollow to access your Twitter account
2) Create a campaign
3) Search for people you are interested in following
4) Filter those search results down to the people you really are interested in following
5) Select people you are going to follow by clicking on the thumbnail (you can click and drag your mouse to select more than 1 person)
6) Add the selected people to your queue
7) Click on Queue from the homepage and go your follows queue.
8) Click the follow button next to each person in your queue. 

To Unfollow, just use the Cleanup Timeline button on the Homepage and follow the same steps as above. 

Hopefully that helps!
