from its first release which I tried and it was a bit buggy.... to the latest release which works fully as far as i can see... this tool has been priceless to assign keys for the game....
the best addition has been the FOV increase from 90..to watever you are happy with. 'm running at 100 and it is WIDER... (in game itsself is maxed out so you can only set it at 90)
ps..I'll take credit for suggesting to add clear bindings tabs.
