buttons in key mappings don't have a sensible sorting order

[User670]

When adding multiple keys in key mapping, the keys aren't sorted in any sensible order.

(top row: (keyboard) A, E, F, G, 1, 2, D, 3, 4, B, C)

(bottom row: (controller) RT, RB, A, X, LT, B, LB, Y)

Suggestion: either make it so that it displays in the order you add them, or make it so that things are sorted sensibly (eg. letters and numbers in order for keyboard; group related things like ABXY together for controller)
