Hi,
Regarding navigation with address bar at the base of phone: At least one navigate forward/right button is needed next to the address bar by default available at all times without hiding it inside a menu option. Only this button is needed because the phone navigation can navigate a page back/left. Although both left are right buttons are preferable.
Consider this solution: make the address bar smaller. You can then fit navigation buttons easily on each side.
Notice that the address bar current width is unnecessary and redundant because it only serves as a select button to bring up the actual bar that you actively type into which itself is wider than the address bar that initiates it.
Therefore decrease address bar width, which serves no purpose being as excessively wide as it is and fit left/right nav buttons on each side of it.
PLEASE!!!!
