Here are some ideas I had: Not so important: - a 2 man capsule like the gemini capsules - a large 4-6 man capsule like the MPCV or Orion capsules - an escape tower for the 1 man geministyle capsule - escape towers have fairings for the whole capsule and also cover the docking port (something like the protective cover: http://upload.wikimedia.org/wikipedia/commons/f/f0/Launch_escape_system_diagram.jpg) More important: - hiding special parts in the VAB and SPH, so I can hide parts in the VAB that I only use in the SPH or that I don't use at all - 2 tabs in the VAB and SPH for the mission flag AND an emblem (mission flag is the flag that you plant on your moons and that you have on your kerbals suit, emblem is the flag that you have on your rocket)
