add new gamecontroller APIs - add mappings after init (or even before w/o using the hint) - get string for axis - get string for button - get mapping string for controller or for GUID - new event to notify when a controller is remapped. (e.g. mapping was changed via the AddMapping method)
Ignore whitespace changes - Everywhere: Within whitespace: At end of lines:
