S!
Looks like the FMB got a LOT new options, which is good. The ReadMe must be pretty extensive on that new FMB

Regarding airfield markers, they could be smaller, even use the tactical markings of that time perhaps?
A question regarding the roads and railways. Are they now properly interconnected everywhere? Can a mission builder now insert car convoys, trains etc. running at the map from one town to another realistically, making it a bit more "living" and give targets of opportunity? Do the cars follow roads now better than in IL-2 where they could try go through fields and whatever...and usually get stuck against a building for example.
Otherwise seems the FMB interface will be familiar to use
