An interesting function would be to be able to extract the list of people in excel, mark who you want to unfollow, and be able to save it, to be imported into the tool later. Because you can't always have time to unfollow everyone at once, and it takes a lot of work to carefully select the people you don't want to unfollow (like pages)

It would be a way to save our "work" of selecting the people / accounts. And be able to continue the unfollowing later.

This idea is already in the works.
Will probably implement this in a more simple way though, and just allow storing selected users in the browser's data.
Don't think excel is necessary here.
