So here's the list :
Checkbox to toggle and allow modifying the separate sensitivity settings.
Separate crosshairs for hands - two different colored circles would do the job.
Separate sensitivity for each hand - same sensitivity acts as the current system.
Switch button to toggle separate sens on and off ingame - again, why cripple close combat if you wanted to snipe for a bit.
Hands will still have the maximum speed of turning defined by the game.(duh) Sensitivity just adjusts at what percentage they turn.
Weapon grouping for hands(circle symbol) divided into 2 groups, of course.
EDIT :Keybind to switch with which hand you're aiming, which is the leading hand. (missed that one)
