This program looks exactly like what I've been looking for. I love that it moves your view and reticule in a 3D environment instead of only moving your mouse pointer to another part of the screen like so many other aim trainers. Unfortunately, I just can't use it. It's practically unplayable for me because there's no option for
reverse mouse Y axis.
I don't even see this feature listed in your to do list, but it's one that I can't play without and I know there are others out there for whom the same is true. An option to toggle it in the configuration menu would be perfect.
Can you add this quality of life feature to your otherwise excellent program? I implore you to do so, the sooner the better, so that I and others who pull our mouses down to look up can begin improving our skills.
