Last year a freeware 3rd party program was developed that allowed users to use either a 2nd monitor, or better yet, an LCD touch Display. Several even had developed a control panel screen exclusively for all of the IL2 controls. I checked it out using the 2nd monitor feature and was really impressed. I never pursued the touch diplay setup due to "gaming budget" versus wife's new shoes but saw several demos and was even more impressed.
The makers of this program even have tutorials for you to edit your own control panels and it is very user friendly. Here are a couple of videos that demo it.
