Twitter today is updating its app to make it easier to switch between the algorithmically programmed Home timeline and the feed that displays the “Latest” tweets. Typically, when users want to move between timelines, they have to tap the “sparkle” icon in the top-right of the screen, then do so again to switch back. But starting today on iOS, tapping that icon will offer the option to pin both the Home and Latest timelines to your Twitter Home page, so you can instead swipe back and forth between the two feeds.
