Two favorite aspects. First, when you tap a tweet in your timeline, it gets selected and a bar of buttons to act on the tweet appears beneath it. Most Twitter clients, when you tap a tweet, present that tweet in a standalone view, sliding over to the right. With Tweetbot’s inline action bar, you can do something like replying or marking as a favorite and then immediately go back to scrolling the list of tweets — no need to tap a “Back” button.
Second — and this is the feature that’s proven the most addictive for me — is that you can slide left-to-right on any tweet to get a conversation thread of tweets.
All this interface polishing is shiny, but does it matter? I worry that we spend all our time minimizing taps and perfecting shiny shadows, and not nearly enough time making software do things tomorrow that we cannot manage to do today.
