Same here. Left handed and keybinds are almost gamebreaking for me also. KSP 1 should be your example of keybinding. I use a 48 key keypad with my right hand and mouse with left. I can use autohotkey to rebind some of these but some keys which i used to be able to use dont work out anymore like kerbal movement and eva jetpack controls, you used to be able to turn pack on and off and use same buttons to move now you cant.
