The service, called Twitter Blue, will give users up to a 30-second window after publishing to change their minds in case they notice a typo or reconsider a message, edging closer to the edit button that has been widely requested by users. It will also give users the option to bookmark tweets and organize them into folders so they can easily be found again. And Twitter Blue will condense long threads into easier-to-read paragraphs.
