Just Arrived is a simple extension that helps you stop scrolling through the same tweets mindlessly. Infinite scrolling has wasted many hours in our lives and "Just Arrived" tries to save some of that time from ourselves.
Just install the plugin. That's all. Every-time you visit Twitter home page, it records the tweets that you have scrolled through that day and dims it the next time you visit Twitter.
