From a hardware perspective, I spent wayyyy too much time re-wiring breadboard circuits with perfectly measured and cut lengths of wire to make them look "beautiful," turning something like this[0] into this[1].
That was a waste of time. Both have the same result, but the ratsnest is always faster. The goal isn't beauty, it's meeting the requirements. The pretty one might be a little easier to debug and transcribe into a schematic for PCB layout and for someone else to understand, but IMO breadboarding isn't the right time for that.
