Tweetscroll is a Chrome add-on developed by Rafael Bardini that aims to enhance the Twitter web interface by automatically showing new tweets without the need to click the "new tweets" bar. This add-on makes the timeline behave similarly to Facebook's News Feed, where new tweets are displayed only if the page has focus.

With Tweetscroll, users can easily keep up with the latest tweets without the constant need to manually refresh the page. This feature is particularly useful for users who want to stay updated on Twitter in real-time, as it eliminates the need to constantly click on the "new tweets" bar.

By eliminating the manual effort of refreshing the page, Tweetscroll provides a more seamless and efficient Twitter browsing experience. It allows users to focus on the content of the tweets rather than the mechanics of refreshing the page, making it a valuable tool for Twitter enthusiasts.

Overall, Tweetscroll is a free Chrome add-on that offers a convenient way to automatically show new tweets on the Twitter web interface, enhancing the user experience and making it easier to stay updated on the latest tweets.
