You'll still have to wait a bit longer for a major update to the mobile apps, but Twitter has today rolled out some big changes to TweetDeck for Mac, Windows and Chrome. That includes some added options for lists (including the ability to create and edit lists from within the application), new activity and interactions columns, inline media previews, and a new "Edit & RT" feature in place of the previous "Quote" option. You can get a quick preview of all that in the video after the break, or simply try it out yourself by downloading or updating the application for your platform of choice (it of course remains completely free).
