Twitter is making yet another tweak to what shows up in your timeline. Starting from today, it will show tweets from earlier in the day under a "While You Were Away" heading.
Twitter says it will work out which tweets are relevant based on "engagement and other factors". If you constantly access Twitter, you may not see it at all. It's likely to take a while before we can work out whether this is a useful enhancement, or a Facebook-style annoyance.
Initially, the feature is only available on the official Twitter iOS app. It will be added to the Android app and the web site in the near future.
