Can we get the ability to remap the back button? Personally would love to change from chat to map. 

The start menu should show all possible shortcuts available in the radial menus. Adding the ability to reorder or remove most items in the start menu (eg: like xbox group tiles) would be a welcome addition.

What you all think?

i like the idea of remapping the back button to show map

Think about a radial menu on the back button, hell yes.
