Lots of changes for Twitter yesterday, including new features for user profiles on its service. “Now marketers can instantly engage Twitter users with rich images while creating a more consistent visual identity across devices,” explained the company. That includes Facebook-style ‘header photos’, as well as users’ photo streams appearing below their tweets. However, another announcement has been causing more of a rumpus. Twitter has redesigned its native iPad app, and it’s a bit of a pig’s ear. “We’ve rebuilt the app from the ground up to make it fast, beautiful and easy to use,” claimed the company, but users have been hollering (yes, on Twitter, but also in one-star app reviews) about the design, which is ugliest in landscape mode. Power users – e.g. marketers running several Twitter accounts – have also been hit by the way the new app hides multiple accounts behind a couple of menus.
