Twitter already hides superfluous replies to your tweets, now it's toying with handing that power to the masses. Software engineer Jane Manchun Wong, who has a knack for discovering what social media apps are building, outed the user moderation feature in a tweet on Thursday. A Twitter senior product manager has since confirmed the function is in development. As shown in screenshots, the update effectively allows users to hide individual responses to their tweets via the menu icon at the top right of a reply. Meanwhile, those reading along can unlock the hidden posts by following the same steps.
