Twitterific for iOS has been updated (Twitterrific 5 for Twitter, $2.99 in the App Store) with a new feature they're calling "muffling" which is an alternative to what's more commonly called "muting" in apps like Tweetbot.

It's a clever way of simplifying a useful function without making it useless. The words or accounts you've muffled are then synced across iCloud to other devices you have. Watch the video to see how it's done.
