1 Siren for Stuka
2 Statistic's of how many wars BISH, rooks and nits have manage to won in the end of each tour
3 Time refuel variation for each aircraft according to its specific fuel internal or external capacity (its 30 sec for all aircraft now on re-arm pad)
4 3D clouds
5 Fly-by view mode during f3 mode in MA (for bombers) or for all aircrafts in DA plus in recorded film (every other decent sim has a fly-by view mode)
And 6 a possible improved special Arena where special features can be tested like a more complex engine management, new damage model, upgrade or revised flight model (that will prevent stick-stiring that is killing the game) and no auto-prevent software. That is if your engine temperature exceeds the normal one because of extensive use of WEP, simply you loose your engine rather than what is happening now where the auto-prevent over heating software takes control.
I think its time to give credits to a careful pilot that he is respectful about his engine (running smoothly). As is now, u just move full forward your throttle and then you just forget about it, same when you use WEP. My opinion this is not the way its should be.
Again excuse my poor syntax and grammar.
