Like the Firefox sidebar, the AIR app allows users to filter the view by type of data, comment or bookmark any entry, and users can also reply via Twitter.
The big selling point for the new app is an inbuilt movie/picture viewer, allowing users to view content without the need to revert to a browser window.
Hands on its definitely one of the nicest looking desktop apps in this space, content is rendered clearly and attractively, compared to say Twhirl which isn’t super pretty out of the box. The app though does lack many of the features that have made Twhirl popular, such as click support for direct messaging in Twitter, color customization, and easy access to archives and user details. In its defense it is an alpha release, and not all users will want for the extra features provided by Twhirl. Definitely worth a look if you’re a Twitter and FriendFeed user.
