I wish there was a better way of following and unfollowing people in Echofon and Tweetie. Echofon takes three clicks and a good few seconds waiting for the follow status to be checked. I realise it takes an extra call to the Twitter API. Maybe, in Echofon, when I view an account in the browser drawer it does the check then and has a dedicated follow/unfollow button rather than the drop-down menu. Anything to make following and unfollowing seamless, quick and easy.
