Twitter appears to be working on a subscription-based service called “Twitter Blue” that would include paid features like an undo button for tweets and a bookmark folder.

Researcher Jane Manchun Wong tweeted about the new feature, which appears to still be in the development stages. The subscription would be priced at $2.99 USD per month, according to Wong.

Wong said that the bookmark collections feature does not have a search or filter function at this stage.

Twitter Blue might also offer an undo send timer for tweets, a function first teased in March.

A Twitter spokesperson declined to comment on the possibility of a paid subscription service.

The social media giant has experimented with several other features as part of its foray into premium services, including e-commerce buttons and a new paid subscription called Super Follow, which would allow users to create exclusive paid-for content.
