This is really more of a want than a need, although as I recall in one of the previous versions you used to be able to rearrange the tray icons on the bottom of the screen (trips, agenda, favorites and settings) to your preference.
It would be great if you can add that feature back and perhaps with the option of removing the dock (leaving more on-screen space for smaller iPhone screens) and placing a single transparent button (like an outline) in the bottom corner of the screen, enabling you to choose which tab to navigate to (agenda, favorites or settings, if maps is selected).
I hope I didn't confuse you :{ Thanks.
