A minor issue. But when viewing a configuration, your image depicting the counter-clockwise twisting motion in the Hydra Configurator might be a little misleading.
I was looking to see how to reload in a few games and I couldn't figure it out looking at the image. It required a counter-clockwise turn of the left controller along the z-axis. It wasn't until I read the xml configuration file that I figured out that's what you meant. In the image, it looks like the controller is vertical, almost identical to your images depicting a turn instead of a twist. It frustrated me for several minutes trying to figure it out. I realize it might be tough to show this clearly, but you might also want to consider drawing that a little differently, possibly from a side view, in case other peope are as dumb as I am. But maybe it's just me and everyone else understood it easily.
Just trying to offer feedback if it can help.
