Fanatec profiler

We are working on a profiler  extension for our PC driver.

All kind of settings should be adjustable and launched automatically when a game starts.

We already have a lot of ideas of what features we want to implement but it would be great if you let me know know of what you want.

So please tell me what are the settings you want to have adjusted. 

How shhould the user interface look like? What special features or functions do you suggest for the profiler?

We will try to implement all constructive suggestions. Thanks a lot in advance.
