Awesome update. For reasons that escape me now, I switched from Tweetbot to Twitterrific when iOS 7 came out. But Tweetbot is clearly a superior client in a bunch of ways. Most notably: streaming api support, and notifications. It's nice to be able to switch back to Tweetbot without leaving my flat blurry world.
My only complaint is the same one I had with Tweetbot 1 and 2: that stupid icon.
