Button input layout

[plin0009]

With the current button layout, the digits are not in order (rows go A-F, then 0-5, then 6-9).

Proposed change: the bottom row has digits 0-3, middle row 4-9, top row A-F. Similar to how a calculator's buttons would look—the digits are increasing when read bottom-to-top, left-to-right
