Invert X axis needs to be added as an option.
More and more games are adding the option in game to invert the X axis. Yes the X axis, to go along with the existing invert look (Y axis) and invert flight (Y axis) options.
Look no further than AAA release Destiny 2. Here's a screenshot. . In the mouse settings you can choose to invert both vertical AND horizontal, genius!
There's a reason they did that; Some folks prefer to play that way. In my case, I NEED to play with both axis inverted for both ground and space combat. Thus when I play now, due to the lack of this option, I am forced to play with the mouse turned around (inverted) and that's just not optimal.
Adding this simple option would make the game fun for me to play where now it's more of a frustrating experience.
So, please add an invert X axis (horizontal) and / or fix the issue with mouse look when raw mouse input is turned off (GstInput.MouseRawInput 0).
