A few minutes ago, Twitter updated its official iOS app to include a number of improvements for the app’s visual appearance.

On the iPhone, Twitter got rid of the margins at the sides of timelines: the app now uses a wider timeline design that feels more natural and less constrained. Comparing the screenshot above with an older version of the app, you can see how today’s new design makes more sense and is in line with timelines we’re used to seeing in other iOS apps.

The tweet composer for iPhone has also received attention, getting an updated look that lets you see how a tweet containing images will look like when it’s posted. The tweet composer, besides revealing photos in your Library in the same area occupied by the keyboard, embeds a preview of a photo you’re attaching below the status update, with an “x” button to immediately remove it and revert to a text-only tweet.

Twitter 5.7 is available on the App Store.
