Totaly yes. a Delta-v calculator is a must before a no-revert button mode, at least for me. I'm not sure if this is because my habits on constructing ships, but at the 0.90 versión of the game I was able to predict the performance of one ship barely on sight. From the 1.0 version to the present, I don´t have this ability any more, and my ships on the earlier career gameplay tend to be short on Delta-v. To have an Simulation mode will be a nice tool to have too. I envision it this way: May be as easy as saving the game on a different file, called "SimulationXXX", instead the "Persistent" one, wich becomes the active savegame file from the push of the "Enter Simulation" button to the push of the "End Simulation" one, wich clears the simulation file and make the "persistent" active again. While the simulation is running, the "real world" clock still ticking for the real time duration of the simulation, which involves the slowdown of the "real world" clock while the simulation runs on time acceleration by the same factor. Will let the Simulate button accesible from the "real world" at any time, this will allow the player to enter simulation mode to plan most adecuate aerobraking maneuver while on route to jool, for example. Too late for modify the ship, but in time to make corrections on the mission planning if you detect a possible source of failure while in the simulation. This adds another interesting gameplay: try to correct a defect only with the actual tools you have... and maybe, if you spend so much time simulating on a time critical situation, left the simulation with only enought time to scream "SSHHIIIIIT!! Salutations.
