Tweebie | InfiniTweet

Sometimes 140 characters is just not enough. That's why I came up with one of Tweebie's great new features: InfiniTweet. Soon, the days of manually copying and pasting your thoughts in multiple tweets will be gone.

As you type and exceed the character limit, the Compose Tweet-window will split up and will put your cursor (including the word you were typing) into a new text field. If you want, you can even let Tweebie number your tweets, e.g. [2/3].
