Threads has announced new additions, which may not be new for X or Twitter users.
Now, you can post GIFs by adding an icon that allows you to access the Giphy image library.
You can create polls with up to 4 options.
Additionally, Adam Mosseri, CEO of Instagram and Threads, has revealed that Threads is testing new features. These include displaying the view count of posts, pinning posts to be featured on your profile, and pinning replies to the top. This testing phase will initially be rolled out to a small group of users to gauge feedback.
TLDR: Threads introduces GIF posting, poll creation, and testing new features such as view counts, pinning posts and pinning replies. Feedback will be gathered from a selected user group.
