FriendFeed Flow Control - all-in-one noise-cancelling add-on - easily "catch up" on the latest from your friends and get the most each time you dive into your FriendFeed stream!
Stay tuned! Feedback is appreciated, let me know if you have any suggestions/comments. In the meantime, have a look at Filters: Friends & Groups.
