Popular Twitter client TweetDeck has just released a new redesign. The update brings several highly requested personalization features, like the option to switch between two themes — a light background with dark text that looks more in line with the traditional Twitter interface, and TweetDeck's iconic dark background with light text. Users can also customize their font size from the settings menu, which offers 13pt, 14pt, and 15pt options. The update is available now for the web app, Chrome, Mac, and Windows — just restart your client to see it take effect.
