That noise is the exact reason why I think the design over the years hasn’t strayed away as captured in the screenshots. One of my favorite parts of using GitHub is that the design is clean and easy to navigate. Throwing twenty widgets on there and cramming everything on top of each other adds clutter and distracts users from being able to visually navigate the page. I can’t speak for everyone, but given the chance, I prefer using GitHub over BitBucket and GitLab because the design is much cleaner and easier to navigate.
