This may not seem like a big deal, but sticky URLs give you the ability to use the browser’s Back button while looking at reports. This makes GA much more usable, especially for people like me who are addicted to the Back button!
In the previous version of GA if you used the browser’s Back button GA would take you to your default dashboard. Now the back button will take you to the previous page. This is a small change that greatly improves the user experience.
