twhirl 0.8.1 released
Mostly a maintenance release, but includes better support for FriendFeed. You can now block a user from the lookup panel, by clicking the corresponding button. Twitter also sends back now if you follow a user when you lookup a username, so you either have a “follow” or “unfollow” button available.
