Just sort of a random thought that could be great for immersion, ESPECIALLY in the historical maps (AVA, FSO, SEA, etc).
Why not allow certain fields to actually have names, rather than just generic numbers? (Air Warrior did this in the later versions).
Example, let's say in a Pearl Harbor map, instead of the Japanese taking off from C20, 22, 30, and 40 they're taking off from Shokaku, Zuikaku, Hiryu, and Akagi. And instead of attacking A5 and A7, they appear on the map as Wheeler and Hickam.
Granted this may not work too well in the Mains, but would be a nice touch for historical setups.
