Since the Chameleon beta first became available, the most requested feature has been for more widgets. The initial build only offered a handful of choices, and while they were all useful, they didn't showcase the launcher's usefulness. More recently, the team updated the application to offer even more widgets, adding a bit more value to the launcher.
Now, however, the launcher has received what I think is its biggest and most important update thus far: the launcher just hit version 0.9.0, which brings the first version of the widget API. Why is this a big deal, you ask? Because developers can now start working on their own widgets just for Chameleon!
