The Options screen allows you to set the behavior of Highway™. For example, on the General tab you can specify your home page, whether you wish to allow popups, and whether you want to make Highway™ your default browser. You can also indicate the maximum, number of web addresses to appear in both your Browser History and your Back button.
The Facebook tab allows you to specify whether your friends' photos should appear on the Friends screen, and whether you want Highway™ to store your Facebook session info for faster access (you won't have to log in to Facebook every time Highway™ attempts to access it on your behalf).  If you choose to have Highway™ store your Facebook session info, you also have the option to be notified whenever there's a new or updated item in your Live News feed, even if you're not currently on the Facebook web site.
