It might be rather expensive, but I will take your idea a step further...I may be unaware that something like this already exists for high level commercial designers, but how about a "smart" breadboard that has an "array" of high impedance digital oscilloscope inputs at every pin connection and every rail point, complete with computer communication and software, so that the equipment senses and maps out the circuit performance, even identifying components, values, and variability, then offers a printable schematic once the correct results are verified by the designer. The component identification scheme might be tricky, with the software offering a list of guesses which the designer would confirm.
