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.

Explains Twitter, the update makes the option to see recent posts "more visible and intuitive to use." It also reduces confusion by making it easier to see which timeline you're currently scrolling, the company says.

The change comes at a time when there's been increased regulatory pressure on tech companies related to their algorithmic recommendation systems and the lack of transparency around their inner workings. For example, a bipartisan group of U.S. lawmakers put forward the Filter Bubble Transparency Act, which would require tech companies to offer a version of their platforms that doesn't leverage user data to make recommendations. The bill wants to give users the option to turn off the tech company's recommendation algorithms if they choose.
