Would you consider being able to change the sensitivity on smaller scales? So if my controller can have a 0.73 input in diagonals at lowest (tested using https://html5gamepad.com and halfway_dead's deadzone calculator), that would mean I would need a 1.369 sensitivity, but my options are only 1.3 or 1.4. I think it would be nice to have the option to place 1.37 sensitivity as I don't want any more sensitivity than necessary to reach the diagonals in full input, since the sensitivities also affect all movement.
will add for next patch
