The ability to mute an account on Twitter has been standard in apps like Tweetdeck and Tweetbot for a while. Now it looks like the ability to hide tweets from an account without actually unfollowing said account is coming to the official Twitter app. Or at least it’s being tested. Twitter is once again experimenting with features via its official app. The mute function hides an account’s tweets from your feed, but still lets direct messages and notifications through.
