Larger return to home screen button and icon option

Currently the return to screen button is a small “X” in the upper left hand corner while on the final delivery options screen. I see users struggle to recognize and press this button to return to the home screen. It would be nice to have either a larger “X’” that could possibly be repositioned to another location or even an ability to change the icon to something other than an “X”…such as a “Home” or “Restart” icon
