Nice idea, Stoney! I like the Boeing PFD layout and associated features in general, but I may be biased.
When I used to play on the PC, I loved Mechjeb. I get why the developers don't want to add an autopilot. I got away with ridiculously complex orbital construction projects without realistic risks. The SAS modes take care of a lot of the pilot workload, anyway. In in real life simplicity is a virtue. Valves stick, CPUs overheat, some pump is slightly less efficient than advertised at a specif temperature, etc. When I was abusing Mechjeb, I could dock thirty modules in LKO without really considering the risks of something going awry.
Since Mechjeb already has the code for this sort of thing hashed out, what about using Mechjeb style parts to increase the display quality on the nav ball as you progress through the tech tree? This would be similar to how different probe cores have increasing SAS capabilities?
