Kerbal Space Program

VAB/SPH design flow currently has no capability or readout of combined data about the craft that is being designed.

Very minimum information should be:
Total Mass
Dry mass
Tons of Fuel broken down by type
Thrust broken down by stage

Additional information to the level of TWR, stage ISP, delta-v and overall drag values would be nice to have.

Feature would assist new players by providing baseline numbers for some of the simpler calculations for rocket performance.
