Threads is getting a “follow” tab, but it’s not the follow-only feed users have been asking for. As described in this post from Thread Developer Cameron RothThe new tab is located on the activity page of the app and only allows you to see a list of users who have recently followed you.
Threads previously listed your recent followers under the “everyone” tab on the activity page, so this isn’t a huge change, it just makes your new followers easier to find. There are also two other filters for “citations” and “reposts”, allowing you to filter recent activity by who republished or cited your thread.
Also, Threads is rolling out translations, which should come in handy if you follow people from different countries. While I don’t see the option yet, Roth says the feature will appear at the bottom of a post, along with the Like, Reply, Repost, and Share buttons.
Other minor changes include the ability to receive notifications from users you don’t follow, improvements to activity feed scrolling, and the option to follow people from the replies section of a post. If you don’t see these changes right now, Roth says you may need to restart your app or wait until the end of the day. However, it is not yet clear when these changes will come to Android.
