Just a couple of things off the bat.
1: We really need a scroll on the Intel screens. There are way too many units listed to display them on one page.
2: All RNAS pilots start with wings and the DSC.
3: All RFC pilots start with wings and Military Cross.
4: Perhaps an auto word wrap on the Pilot's Log. Right now, a lot of the text runs out of the book. To get it to fit you need to drop down to an 8 pt font. Of course messing around with the font looses the next page link. And the front of the book looks kind of odd in 8 pt.
5: I get quite a few missions with way points over 225 km. These occur with all type of missions (intercept planes over England, join bombers to escort at a gather point 200 km behind the lines, etc). Unless I've missed the tankers for air refueling, these missions don't really work.
I know that these things are picky little things but since you're working on a new version.....
Oh, Pioniere, the aces are handled completely differently than normal pilots. Their medals can be added quite easily if one knows the medals and dates awarded.
