If you have more than 1 project in Regpack, it's easy to switch between them. Head to the bottom left of the screen and locate your project name on the black bar. Click it, and you can view all of your projects. If you have more than 6, click "View All" to view all of your projects. There is a search bar so you can find a specific project easily.
You are also able to view project-level next to the list of the projects in this view, including orders, payments, balance, and the total number of users or groups.
