I'd have to get in the game to see which preset I based my current setup up on, but yes, I use an Xbox controller also.
I've made several changes to button layouts, particularly to the SRV. I couldn't stand the trigger and LB/RB fuctions being swapped between ship and SRV. I also made some changes to basic flight as far as pitch/yaw/roll. I didn't like the default layout. Other functions like flight-assist were also changed. I'll get some screen shots and post them up later if it helps.
