An option that is sorely needed to properly support controllers is the ability to invert the y-axis. I find myself playing PC games more and more from the couch and hooked up to my big screen TV vs. from a desk with mouse and keyboard. With this setup, mouse/keyboard is not convenient nor is it comfortable, making full controller support essential. I know a lot of PC gamers are migrating to the couch as well, not to mention personal preference that some have for a controller vs mouse/kbd.
Is this planned for Arma 3?
