id like:
-hi alt contrails
-slightly better graphics for damage
-hit sounds that vary between 3 sounds(ie if 30 cal you can have 1 of 3 30 cal hit sounds play)
-MUCH larger explosions of bombs

-smashed glass and instruments if hit
-intruments that when hit stop working
-dust on the floor kicked up by wheels or ditch or vehicle tracks
-possible .camoflage command for GV's that hides them under netting?
(if dust was added i think all vehicles should be allowed not to show up as a DOT.Instead with the dust it should make them highly visible but if they stop the dust stops and they again become hard to find)
-propellor damage if you go HO and other explodes (peices hit your prop). this way if you continue to HO after 2 or 3 your prop becomes unstable and you have to ditch

-night light in cockpit (red prefferably or green please) to make cockpit less 'glowy' at night
-flames inside plane that can kill pilot if he stays in it
-more positions on the map for hull down in panzers(ie sandbag positions or ditches etc near bases).
-new large map but less bases! cant we have the same number of bases but with more spots for vehicle battles or large sea zones for carrier to carrier battles.
-better flak or ack on CV to combat vertical attacks.(ie level attacks stays same but dive vertical on CV and it pops you much better)I dont like this but might be the only way to stop this dumb kamakazi stuff killing the fleet fun.
hehe ok thats about all i could think of in terms of cosmetic type stuff.
I agree wholeheartedly with your list mitsu (wtg)
