I know most people prefer to play with a HOTAS, but I really like my couch and my Steam Controller.
With it's extensive configurability, I rarely need to reach for the keyboard anymore.
Here's my current controller configuration "Yeshe McGermots' trucking layout"
As of 20170929 all I really added to the standard layout is a profile switch on "left stick hold" for those functions I found I needed most often to reach for the keyboard for.
Upcoming: A third profile for targeting and voice chat controls.
If you have any questions about configuring the SC or maybe have a neat trick you would like to share, here's a place for that now
