StackTopReorder is a free Chrome add-on developed by Travis J that allows users to modify the top bar of the Stack Overflow website. With this add-on, users can customize the placement of various elements in the top bar to suit their preferences.

The add-on moves the multi-collider (site picker) to the top left, along with all the "action" drop downs. It also moves the questions, docs, jobs, users, and search bar to the top right. Additionally, it places the logo beneath the top bar, ensuring that it does not scroll with the page. Furthermore, it reverses the order of the "action" drop downs.

If you are a frequent user of Stack Overflow and want to customize the top bar to enhance your browsing experience, StackTopReorder is a useful Chrome add-on to consider.
