TweetDeck 0.31.3
Iain Dodsworth has released the latest version of his Adobe AIR-based Twitter client, TweetDeck. Changes include a revised notification system with a new pop-up preview window, support for keyboard shortcuts, an added Followers column, and the capability to set notification preferences per column. Also, several issues have been addressed, including a bug that caused the spell checker to be unavailable for some users, a bug that prevented certain URLs from being automatically shortened, and a bug that prevented users from entering messages longer than 140 characters (messages must then be edited to no more than 140 characters). A full
list of changes is available on Dodsworth’s Web site. (Free, 2 MB)
Why would anyone use something written in Adobe Air?
Because none of the Cocoa-based Twitter clients I've seen offer groups (that work), which are utterly key to how I use Twitter.
