Twitter Tests New Tabs for Lists and Bookmarks, New 'Topics' Shortcut

As Twitter continues to work on its proposed topic streams option, which would potentially enable people to swipe across to view curated tweet timelines around specific subjects, it's also looking at new ways to help connect users to more content-specific listings, with a view to increasing engagement through discovery. This week, social media expert Matt Navarra (who, incidentally, spoke to Twitter's Sara Haider in the first episode of his new podcast) spotted two new Twitter tabs in testing - one which links straight through to your tweet bookmarks, and another to make it easier to view your lists. As you can see here, there are two new tabs added onto the end of the display, which, if rolled out, would be a major update, given that Twitter has maintained its simple, four tab display since basically its inception.
