The only problem is this uses numpad and as a laptop user we don't have numpad so maybe it would be easier if it uses 1, 2, 4, 5 instead of numpad 1,2,4,5?
In the future I will try to implement various control configurations.
At the moment you can use the numlock to use the 'J' 'K' 'U' and 'I' buttons.
ok thanks!
