To access the new media timeline, you can scroll at the top of the regular timeline and – both on the iPhone and iPad – hit the media button next to the search bar. In the media timeline, status updates containing pictures or videos will show their respective media fully expanded inline, ready to be tapped to be viewed in full-screen. Imagine a mix of Tweetbot’s existing style and Instagram’s photo feed and you get the idea.
This is a really clever way to view all the visual content of those you’re following. Absolutely sublime.
