Hey @blastermaster73
I don't often change buttons on controllers myself, but I did find it pretty awkward to do on a different game myself recently where I had to keep moving pretty much every button due to moving one thing that ended up sharing with another button, then that one shared with another button, and so on, so I think I understand where you're coming from with this.
Do you think it would be easier and less confusing if there was an option for custom controls where the list of commands is shown but everything is blank (no button assigned), and you can't use the custom controls until you've filled in a button assignment yourself for each one?
