Undo Tweets May Have a 5 / 10 / 20 / 30 Second Timer

Twitter is working on the ability to adjust the duration of the Undo Tweet timer: 5 / 10 / 20 / 30 seconds. It’s also possible they are working on a tweet preview that a lot of people are asking for.

NOTE: The feature was likely discovered by reverse-engineering the app to find hidden features and security vulnerabilities, so while it’s possible this may come up as a feature in the future, there is no guarantee that it will.
