After the usually post sortie message (you landed successfully, you ditched, you're dead because you where stupid...) it would be nice if the perkies earned for that sortie were also displayed.
Not so much because I'm a score potato, more that I always seem to remember I wanted to go in the hanger and look at perkies earned after I've taken off. If it was in text buffer I could just scroll up and find the message.
As long as I'm wishing for memory aids. How about a flashing idiot light and siren for when at full power in autoclimb and the landing gear is down. Sometimes the players around me are too busy pointing and laughing to tell me.
