Your browser's address bar keeps track of the current status of Pozi, including the map position, any layers you've turned on, and what panels are currently open.
If you want Pozi to open up with a particular starting point, you can save the settings in the address bar by clicking the star button in your browser's interface.
Now you've captured the current state of Pozi, you can return to it any time using your new bookmark.
