(Stop at, last stage, optimize stage)
(2,2,2) Reaches desired orbit
(0,2,2) Reaches desired orbit

- intended.  these are the right settings to use.

(2,2,off) If nothing is set to optimize, it will just go all the way through the first and second stages (but not start the third or fourth), injecting the craft into interplanetary space

- intended, the target box changes to burnout altitude and FPA to show that you're doing a whole-rocket-stage fixed burntime launch.
