Twitter today confirmed that it is working on an option to cancel the posting of a tweet (undo send), immediately after it was sent.
A spokesman for the California-based giant confirmed that tests were under way after an analyst, Jane Manchum Wong, revealed the information on Twitter.
She posted a screenshot of what this feature might look like. A blue bar may appear during the tweet, giving the user a few seconds to "cancel" their message before the timer runs out.
The "cancel" function would allow a problem to be corrected immediately, without any complications in the case of modification, after a message has already been retweeted, for example. It would look like a similar option in Gmail, Google's email service.
Twitter did not give an indication of a possible launch date for this feature, but according to US media, the service could be made available to prospective users for a fee.
