It would be nice to be able to plan a flight to a defined target orbit even before launching.
For many missions, launching into an approximate parking orbit and then planning the flight is sufficient.
But for more "interesting" missions, the correct parking orbit is not obvious, often requiring large corrections or several relaunch tries when guessed wrong, and sometimes it is quite inefficient to go to a parking orbit first instead of the target orbit directly, like when a low-thrust upper stage cannot easily reach a LEO, or because of orbital precession. Or to reach a lunar NRHO the initial orbit would need to be several degrees away from the lunar plane but it's difficult to guess in just which way.
The way I would like this to work, is that a landed vehicle can access the flight planner, but the first maneuver created would plan the launch in the following way:
Maneuver time selects the launch time
Original flight vector is the surface vector at that time
Maneuver delta-v is then applied to the surface vector
If an additional setting could be made, it would be the desired periapsis at launch.
Without the periapsis setting this will create an orbit with periapsis near the ground, and obviously it can't plan the required gravity turn, but these are basically part of every launch and shouldn't be a problem.
However this allows playing with the planned inclination and LAN of the initial orbit and planning the further mission, before launching into the proper orbit, and makes it easier to plan a correction after launch to make the rest of the mission work.
Especially useful for:
SSO and polar orbits
Missions to larger halo/lissajous orbits
Missions to frozen lunar orbits, or rescue mission orbits
Direct missions to lunar surface locations
Interplanetary transfer planning
