I seen that many people have my same problem: using standard in game icons with xbox controller.
So I decided to modify that standard icons to set xbox icons.
For the moment, I modified only the ingame icons as you can see (in future I can modify the rest of icons if necessary):

For now, consider it a beta version cause i have tested it only on my pc.
You should not have problem, but if you did, tell me and I will try to solve the problem.
Well, here it is the link:

UPDATED 1.1 VERSION PC CONFIG VERSION
I changed also the menu' icons and ingame play calls icons (for players)



The last icons, for now, is not editable ( RF1 RF2 LF1 LF2). I try to work again and find, if possible, the way to modify that icons too.
