Twitter is working on a feature that could offer users a short window of time to rethink posting a tweet even after they hit send. CNN reports:
The company confirmed to CNN Business on Friday it is testing an undo option that would potentially let users retract or correct a tweet before it’s officially posted on the platform. The feature was discovered by Jane Manchun Wong, an app developer who has a strong track record of uncovering new tools on social networks before they’re released. Wong posted a GIF on Twitter that shows a blue “undo” bar appearing beneath the words “Your Tweet was sent.” (It’s possible the feature could change before it formally rolls out – if it ever does.) It’s not quite the edit button users have long requested, but it’s a step toward helping users proactively catch errors and slow down before sending impulse tweets.
