I like how share sheets have been implemented in the app. Like Tweetbot, you can tap & hold on links in the timeline and you'll get action and share extensions in exchange for the ability to preview the full URL; you can also share directly from web views. What I like, however, is that you can tap & hold any tweet to instantly show the share sheet and pass its URL to extensions. I often use tweets as todos, and being able to save links to tweets with extensions in Twitterrific is fast, easy, and, overall, nice. Especially on the iPad – where Tweetbot hasn't been updated and the Twitter app doesn't support native share sheets – this aspect of Twitterrific is extremely welcome.
