@crazyg I didn't want to be negative, but I'm also not too impatient of seeing this game in TA. Maybe a reworked custom versions with also the biggest historical blunders reworked (Berlin closer to Moscow than Paris, etc., etc.), yes.
On the other hand, I think supporting this specific thing would be a general great improvement:
Fighters are a land unit to let them stay in conquered/enemy territory and be able to load on transports, so if you want to fly over a Sea Zone or enemy-controlled territory, use edit mode.
Both the ability to land transport air and the ability to stay in conquered, and, possibly, also giving air the ability to conquer.
This way, by the way, cavalry, if added, can be "air" too. Also think about the applications in term of Dragons or Helicopters, etc..
Not terribly impatient for the game itself, but whatever adds options and stuff a mapmaker can re-mash up is sweet. The aborted making of this game has actually already added up a series of additional options, some of them really helpful, like the phase steps, that have found good use in several custom maps.
