Great job malkuth! I have a couple of ideas. Feel free to use them if oyu like them: Suggestions for missions. SSTO: I rather miss missions that require the use of SSTOs. Maybe as part of the satellite missions, where you receive extra bonuses for deploying and/or recovering a satellite with a SSTO. Storyline for lack of a better word: Contracts that build on already accomplished missions. Maybe add a rover to a base, add specific modules to previously established space station. Move satellite to new orbit (with SSTO for extra Bonus) and so forth. Allowing for other mods. With KAS you could add EVA repair missions. In Kerbin orbit that could again include extra bonus if accomplished using a SSTO. With Scansat, you could earn bonusses for completing specific mapping missions.
