Twitter is actively working on a “big overhaul” of its TweetDeck platform, which lets you arrange lists and feeds into easy-to-read vertical rows, and it plans to share more about the project publicly later this year, product chief Kayvon Beykpour said in an interview with The Verge published Tuesday.

TweetDeck, as one of the oldest and originally third-party account management apps for the platform, hasn’t seen much in the way of design or major feature changes in years. The app launched 12 years ago and was acquired by Twitter in 2011, and it’s more or less still the same column viewer for your various Twitter feeds it started as. Mostly, Twitter has ported over new functions added to its main website and mobile apps while keeping the core TweetDeck design relatively static.
