I feel there needs to be a way to build a legacy for your flights. It is very satifying to land on the moon or send a sattelite in orbit around a planet, but there is no record of it. I would love for there to be a way to take photographs on the flight, from a camera part or from the point of view of a kerbal. To be able to collect rock samples and bring them back, and for all of these to be put into a mission log that can be reviewed and maybe even have a museum where you can view your flights. I know this is quite a large feature, but I feel it will make accomplishments in the game much more satifying and can serve as way to show your friends the game to possibly reach more customers. I am a developer so I may look into making this a mod on my own but I wanted to see what other thought of the idea as well.
